Leave your response as a comment on this post by the beginning of class on November 8. Remember, it only needs to be three or four sentences. For these weekly questions, I’m mainly interested in your o […]

The biggest challenge for me is when I tried to visualize my assumption from my data analysis. At first, I found it was hard for my to transfer numbers to pictures, and to make the data easier for the public to perceive. I have to acknowledge that the readers are mainly average people, who might not encounter Tableau or any data analysis tools. Therefore, I used common indicator and easy charts to illustrate my points. I also used related objects of the theme to draw more attention and engage people to read my infographic.
-
The biggest challenge in assignment 4 was the format of the data in excel file. I spent a lot of time to clean the data before creating the visualizations. The example of the format problem is that the date was in the format that I cannot use to create the visualization. Then I need to change them into the right format, which was a very time-consuming process.
-
The biggest challenge for me was trying to figure out what infographics we had to choose for our visualization. We all tried to go online to various websites to find which infographic would be correct for what we were trying to solve. We decided to create our own infographics by drawing on the paint tool online. We then eventually found out which one we would use for the assignment. It helped a lot that everyone in our group was finding the right one and drawing it out. Eventually, we were resolved it.
-
The biggest challenge in assignment 4 was cleaning data. Many movies are classify into 3 or more genre, it is hard to create visualization I have to classify the genre of the movie and clean usefulness and wrong data. This process cost a lot of time because of the huge amount of data.
-
The biggest challenge in assignment 4 was cleaning the data. Because the movie excel spreadsheet consisted of so much data, there are clearly things to clean up. In order to understand the data in a better way, we had to narrow it down to specifics as well as filtering. This was challenging because cleaning data takes time and effort and it can also become frustrating at times.
-
One of the biggest challenge in assignment 4 was trying to figure out how to start because there were no specific direction or layout of what we should do. All of the in class assignment had a set of directions but for this assignment it was more open. When we all met up to start the assignment the first time, I was confused on what to put in tableau for creating the graph.
-
the biggest challenge in assignment 4 for me is to find weather, times and history event information for the question requirements. At first we were really confusing on how to find the specific information on each requirement called. After that we finally find a way to come up with combining weather and history event together on a website and used it for the assignment.
-
the biggest challenge that was faced was cleaning the data. Each member of the team was assigned a movie category. my category was Horror. i had difficulties cleaning the data because it was so much…categories within categories ( horror and its sub-categories, such as drama, comedy, parody, action ,adventure and much more) i was eventually able to clean it through filter in excel and be productive in my group work.
-
The biggest challenge for me in assignment 4 was cleaning the data on the excel file. I could clean one set of data without messing up another data. I would try to just use data for Drama movies but it would do it for all the movie genres. I found it to be easier to clean the data set on Tableu it self.
-
The biggest challenge for me during assignment 4 was trying create data visualizations in tableau. There were certain visualizations that were easy to construct and supported the points we were trying to make, but as the data got more advance, the construction of visualizations and charts became much more difficult. Also, it was very difficult to construct concise visualizations that directly related to the questions we were trying to answer.
-
The biggest challenge for me during the assignment 4 is to analyze the data professionally and accurately. The challenge my team chose was from Comcast. When dealing with the giant dataset, Excel and Tableau skills are significantly necessary. However, as a newer and a learner of Tableau, I made mistakes and errors during the process. Therefore, it took us a great deal of time to correct possible errors and check the reliability of our analysis. Another challenge is to meet periodically with the team members, the different majors and different schedules we had affect the performance of our infographics.
-
The biggest challenge for me in Assignment #4 is Piktochart is a software which take time to get used to, because the function is limited and not fully convenient. The way we solved this problem was I asked my friend who is more familiar than us on using this technique in order to help us take advantage on Piktochart as much as possible. Also, it was challenged to get every team member agree on a fragment of the design due to different members have various perspectives. Fortunately, one of our member major in Arts & Music who usually has better design thinking and is capable to make a final decision. Furthermore, it was not easy to meet with other team members frequently due to we all in different majors and have different schedules. If we really could not have a group meeting, we just worked separately and tried our best to finish our own work firstly and then met with each other. Therefore, we could combine our work together without changing that much.
-
the biggest challenge in assignment 4 for me was how to use the data given to answer the questions. in other words, how can I answer the questions by visualizing the data I have. Coming up with the right answers to the questions was the longest part for me. for example, how to use the Pfizer data to answer their questions about the effect of smoking on society.
-
The biggest challenge my group encountered while working on Assignment 4 was creating the visualization portion of the project. Creating the graphs also posed a challenge however once we figured out what data sets we wanted to use, the graphs were made. Once we started crafting the infographic it was challenging making the graphs look pleasing. We had to brain storm and decided photoshop was the best option. Once this was done the whole infographic looked better.
-
The biggest challenge for me is making sure a fundamental direction to analyze data. Too many data over there, we spend huge time to choose some data that we think it is useful. And we also try many ways to analyze. But picking up a way that four of us all agree is very difficult. We wast huge time on finding suitable analyze way.
-
The biggest challenge of assignment 4 is to select the useful data. I screened out the bad data and selected the data that could be useful to the problem we tried to solve. And turned the data that I chose to information, and analyzed the information we got. Then we set a threshold to narrow the range of information that should be analyzed.
-
The biggest challenge in the assignment 4 for me is to analyze the data correctly and briefly. It’s would be a totally different result if I can’t tell the information from data in a right way, the audiences would think in a wrong way about the data, then they would never get the true information they want. It’s very important to lead people to really understand the information that comes from the data.
-
It sounds kind of silly, but our groups biggest challenge was trying to figure out what exactly the professor was looking for considering this assignment didn’t come with a straight guideline. This was more of an open ended assignment which allowed the class to have freedom in how their assignment was constructed, which can be fun, however, it can also make the project a little more stressful because you don’t know if you’re giving the professor what they’re looking for or if you are not doing something right. So I think that was the biggest challenge for our group.
-
One of the biggest challenges for me was deciphering which data to use and how to use it. Since a lot of data was missing it was important for me to try and keep the analysis as unbiased as possible with the numbers we were given to ensure a good read on our information.
-
The biggest problem in assignment 4 was trying to navigate through the data and determining what need to be used and when, along with if certain parts of the given data needed to be cleaned. To resolve this problem we experimented with many different ideas, something like trial and error until we came up with what we found to be the best way to go about it.
-
The biggest challenge for me on assignment 4 was figuring out what to do with the data given. It was tough to decide what we wanted to create on a graph with the data given. We resolved this problem by thoroughly looking through and cleaning the data to determine how we wanted to show our charts.
-
The biggest challenge of assignment 4 is to choose the right date to analyze it. Since we have too much data in the website, we cannot choose the best one in a very short time. In addition, there are a lot of wrong data that we cannot use in a directly way, so we should delete those data that will affect our results.
-
The most prominent challenge was trying to find the best approach for counterarguments. As a team, we did eCommerce and us to think outside of the box and understand why people would form their arguments, to begin it. Instead of trying to find the best answer, we directly gathered as much data supporting our thesis and conclusion. For instance, one may argue that people in affluent zip codes order stuff more than not so fortunate people. A counter-argument could be that it’s just coincidental and those people in the less affluent could just be wealthy and bit order as much. Or even is close to a shopping mall and have resources in their reach, so they do not have to rely on the internet. There are lots of ways to go by this, and as a team, we combated these type of issues.
-
The biggest challenge our group faced during assignment 4 was coming up with good graphics. To fix the problem we first eliminated outliers from the graphs by excluding them. Next we created a calculated field to further how good the graph was at displaying our desired information.
-
The biggest challenge for me was how to use the given data to answer the questions and then use the tableau to create the visualization.
-
The hardest part of Assignment 4 was figuring out a general plan when starting out. Going through all of the available data and determining which sets were most important proved to be difficult. This especially made it difficult to figure out a plan for how we wanted to present the information later on.
-
The biggest challenge was knowing specifically what to use and cleaning up the data. It was very time consuming and honestly, it should’ve been the only assignment for the class, at least the first half. All the lessons we learned could’ve been applied to this one assignment and it would’ve definitely helped us understand it more. The issue as to why I didn’t really know what to do is because the in-class assignments tell us exactly what to do instead of actually learning what we’re doing.
-
The biggest challenge in assignment 4 was figuring out how to make our graphics clear. Tableau is a software that we’re all still trying to get the hang of so it wasn’t easy to translate the questions into graphics. Eventually we came together and figured out a way to make our graphics represent the questions we were answering. It was all about team work by the end of the project.
-
For me and my group we found that the hardest part of assignment four was creating an infographic. We struggled to use the website Piktochart that we had worked on previously in class during one of the in-class exercises. We found it hard to make graphs and other graphics on the site itself and and had to end up importing graphs from Tableau that stuck out visually and did not fit the color schemes or themes of the rest of the info graphics.
-
The biggest challenge is to use the Piktochart design. Because it takes a lot of time to look for the proper background and section to correspond our team topic. Also, I need to select the best color for the background.
-
One of the biggest issues we faced was deciphering all of the data. There was a huge amount of data which contained multiple errors and it was very difficult to pick my way through. Once the data was deciphered it went off without a hitch, but this initial challenge was very tough to overcome.
-
-
One of the biggest issues we had was just trying to figure out what to do. When we did figure out what to do, getting the right kind of chart was difficult. We eventually figured it out and it turned out to be not that hard. As a group we thought we had to make a poster on piktograph. When we found out that we didnt need that either, the assignment was okay.
-
The biggest challenge in assignment 4 is cleaning data.Because there are lots of dirty data in the database, I had to spend much time to clean the dirty data or uncompleted data. I use filtrate and sort button to find the dirty data and clean the data.

The KPI that I use daily is the Social Media Metrics that measures and analyzes the performances of Temple Consulting Club since I am the one who runs the club’s Facebook page. It is specific and measurable because I can see the exact number of likes and number of people reached by our posts. From those numbers and datas, I can know which posts are more attractive and easier to get people’s attention. It is achievable because we can draft our social marketing plans based on the results of our performances in the past. It is relevant because we want to promote our club, which is established recently, to Temple students, especially students in Fox. It is timely because we have the data from a period of time and can predict the trend in near future.
-
The KPI that I use almost everyday is my timer/ clock app. It is specific and measurable because it lets me know when to wake up/ go get some rest. It is achievable because I can set up alarms if I need to get a task done or step away from a task. It is relevant because I need to manage my time well if I want some leisure. It is timely because well, it is my time lol.
-
The KPI I usually use in my daily life is checking the weather application every day, so I can select the right outfits to wear on that day. It is specific and measurable because I specifically look for the temperature in which is measured in the actual number. It is also achievable and relevant. For example, the application also shows the percent chance of raining; that makes me know that I need to bring my umbrella. Finally, it is time phased because the weather will be reported in a one-day period, which is a relevant period.
-
A KPI that I use on a daily basis is the time and mph on the elliptical at the gym. I use the mph to determine how fast I am moving and correlate that with the time being shown on the timer. As I continue to go to the gym, I use these measurements as a way to track how much I approve my stamina and health. The faster I can run a mile shows improvement and by the next time I go to the gym I try to beat my time that I had the previous day. Luckily, this gives me motivation as well to keep pushing myself.
-
The KPI I use is my Wells Fargo online banking app. It is specific and measurable because it tells me the details of how much money I left in my account, how much I withdrew and how much I deposited.

It’s specific and measurable because it tracks my location from one destination to another. My location is on all the time and the app tells me when I’m walking and throughout the day when I was the most active.It’s achievable because it tells me whether I achieved my desired goal for steps and whether I need to walk more as it also does a weekly calculation. Its relevant because it tells me if I need to walk more for the day. I like completing the steps per day so I move around more. It’s time variant because it gives me an alert daily and weekly of whether I completed the task for the day or whether throughout the week I need to be more active.
-
One of the KPI that I usually use is a note app. It helps me track and manage daily events, such as assignment due date and test date, etc. This KPI is specific and measurable because it shows me when should I start doing an assignment before its due date or when should I plan things ahead. It is achievable and relevant because this note app provides me detailed information and processing time for my daily events. I can mark it “Finish” when I complete a task. This KPI is also time-related because I get things to do every single day, and this app will refresh itself on a daily basis.
-
A KPI I use frequently is the steps counter that comes with Health app installed in every iPhone. This helps me keep track of the exercise I’ve done on a daily basis, and tells me how much more or less work needs to be done in the gym depending on the amount of fitness I performed on that day. This KPI s time-bound because you can see it daily, weekly, or monthly as you would choose, and it is also measurable as it tells you how many steps you’ve taken and let’s you see your overall performance for the day, week or month.
-
My most common KPI is my sleep app on my phone. It monitors how many hours of sleep I get each night and can tell me if I am getting enough or not. As it notices shifts in my sleep pattern it questions if it is due to me doing too much work or if it is from me being busy. It will suggest better sleep habits to me. It will also ask me questions about how I feel to see how much sleep I perform best on and how much I should be getting.
-
One of the KPI that I use frequently in my daily life is the calendar on Canvas. This calendar helps me to remember and make plan on when I will have exams and what is the due date of my assignments. This KPI is specific because it directly shows me what should I do on that day or finish before that day. It is also measurable because I can make the most suitable plan for myself in order to finish my assignments and review for my exams through checking the date. This KPI is achievable because I can upload reminders for myself about what I should prepare for next class. It is relevant to my grades due to I can check whether I finish the homework or review for my exam or not. It is also time-phased because I can organize each of my day reasonably for different subjects.
-
A KPI that I use frequently in my daily life is Yahoo for my fantasy football sports league. It’s specific and measurable because it shows me where I currently am in the standings of my league as well as the average points per matchup that my team scores. It is achievable because I get to decide what players to start every week as well as what players to pick up from the waiver wire or what players I want to drop to free agency. It is relevant because it is football season currently and a ton of people, along with myself, love to play fantasy football. Lastly, it is time-phased because it gives me live updates of my players’ performances during their games and allows me to set my starting lineup days before games actually start and I am not able to change players around to starting/benched once their game has begun.
-
A KPI that I use somewhat regularly is the information found in the degree audit reporting system (DARS) on TUportal to check my progress towards graduation. It is specific because it has information about each class, when I took the class, the final grade, my GPA, and how many credits I’ve completed and how many I have left to complete, to name a few examples. All of these are measurable and they are relevant to indicating my academic progress. The information also tells me what goals I have to reach in order to graduate, such as specific types of courses I need to complete which is presented as a bar graph and is presented throughout the page with check marks indicating the courses I completed and an ‘X’ for those that I have not completed. The information is time based because the amount of credit hours is indicated for each course.
-
A KPI I frequently use is the amount of calories consumed that is tracked on the calorie tracker app. It is specific and measurable: it helps me find out how much calories each food (I consumed) contains and when I add them to the list, the app would tell me how much calories I have left (can consume later). It’s achievable: I can make better food choices by looking at the calories and try not to overeat or eat less than the required calories per day. It’s relevant since it affects my body (living style). Lastly, it’s also time-variant because I can look and how much calories I consumed everyday.
-
A KPI I use in my everyday life would be my Fitbit Alta HR. The Fitbit tracks my sleep patterns, which I can then go through and examine via my Fitbit app. While setting up my Fitbit I entered the desired number of hours of sleep I want to get per night. This feature is specific because it tracks when I fell asleep, when I was awake during the night, and when I wake up in the morning. It is measurable because it tracks how much sleep I get during the night. My goal of the number of hours of sleep I get a night is achievable and can be altered if I feel it is too many or not enough. This is relevant to my life because without sleep I can’t function so it’s important for me track how much sleep I do get every night. My sleep data is stored in my app, which dates back to when I first set up my Fitbit. Every week and month I receive an average number of hours I’ve slept during that time period.
-
A KPI I use almost every day is the Activity App in my Apple watch. It is specific in measuring my movements, exercises, and stands. Measurable by calories and heart rate and achievable because it measures my own achievements and I can set a minimum goal that is suitable for me. Relevant because it impacts my health and time-phased to for everyday activity.
-
Weight is a KPI that is good and can be used regularly to help measure how active you have been and how active you should be. Its also a general measure of health and can be used by physicians to base dosages of medicine.
-
The most regular KPI for me is the safeguard of my computer. It will automatically detect the conditions of the computer as long as I use it. While there is a virus, the safeguard will remind me to kill it. When I use computer for too long, it also will reminder me if the temperature of CPU is too high. Through these smart functions, the safeguard helps me with the maintaining of my computer so that I don’t have to buy new one so quickly.
-
A KPI i use everyday is a catapult in football practice everyday. The catapult measures my sprints, how long i ran for, how much my workload was for the practice. It shows if i ran over 14 mph and that determines the amount of sprints I had. If I had a high players workload that means I had a very productive day.
-
A KPI i use it on my online banking app. It is really basic and specific because it provides me information about how much money in my account, which division i spent my money in and most importantly is the different between the outflow and inflow money of my account. With KPI i can measure how much money i earn and how much i spent it in order for me to spent it perfectly.
-
A KPI that I use everyday is my body weight scale. It is specific and measurable because it tells me exactly how much I way and the measure is in pounds. The scale is achievable because I can figure out whether I need to gain or lose weight, so I can eat and workout the right way to either gain or lose the weight that I want. It is relevant because I want to know how much weight i may have gained or lost over the past few days. Lastly, it is time-variant because I can look at my weight any time i want.
-
One KPI I use almost every day is the alarm clock app on my phone. This app is specific to me because I can set whatever time I want on it and it has a relevant purpose to me – to wake me up and make sure that I am not late to any of my daily activities.
-
A KPI I frequently use is the checking weather app. This app can tell me the real-time weather before I go outside. Also, I can check the whole day and the next week so that I can make prepared for the next week. It can predict the percentage of rain and the humidity. It makes me know the highest and lowest temperature of the current day.
-
The KPI that i always use is an app of my phone, it can record your step number. It is specific and measurable because i can know how far i walk per day. It’s achievable and relevant because it shows how far i have been finished, if i did not reach the goal that i made, it will remind you to complete your goals. It’s time-variant because i can check it per day or once a week.
-
The KPI I use the most is either my USAA banking app, or the digital gas gauge in my car. It tells me how many more miles I can drive with the amount of gas I have, to make sure I do not run out of gas and get stuck somewhere. Without it I would probably run out of gas in random places, makes my life much easier.
-
A KPI I use very frequently is my PNC banking account app. It is specific and measurable because it tells me how much money I have in my account. It is achievable because it helps me not having to take cash out and instead to use money virtually. It’s relevant because it helps me pay for my expenses at school and in life. It’s also timely because it lets me know of my transaction history in case anything looks incorrect.
-
An example of a KPI I use on a regularly is the calories burned counter on the treadmills, elliptical, and bikes at the gym. It is specific and measurable because it shows the amount of calories I worked of while exercising. It is achievable because I can change my work out in order to burn more calories. It is also relevant because knowing the amount of calories a burn is import to knowing if I had an efficient workout and that is important to my health. It is timely to as I can then keep track of my calories burned for the hour, day, week, month.
-
My battery percentage on my phone is a KPI I use regularly. It is Specific and Measurable, the percentage is precisely determined. Its achievable because I can use my phone more or less to get to a certain percent. The relevance is that my phone is something I use throughout the day everyday. I can check my battery every couples minutes or hours.
-
A KPI I use every day is “weather” app on my phone. I check the weather to get dress and it also tells me if I need to bring an umbrella. The “weather” app helps a lot with checking the temperature and provides me conveniences.

Once a week for my stats class we have to work on excel spreadsheets and I usually do not save my work till I am done because only when I want to export it to an e-mail does it ask me to save. My laptop was low on battery and on the night the assignment was due, I transferred the information on excel to a pdf and exited out of the excel thinking I wouldn’t need it so I didn’t save. After I turned in the pdf, my laptop shut down. When my laptop came back on, my professor said that he needs the pdf and the excel sheet. So I rushed the assignment within an hour. Now I save after completing every step of the assignment.

I have never made one of these mistakes. However, I think the most important to avoid is clicking “yes” without carefully evaluating the message that says. Many of us can do this mistake when they are busy and try to finish their work for example. Sometimes the message is not specific so you actually make an error that can delete metadata and configurations, not just data.

I have entered data into Excel file with the wrong format. I was creating a spreadsheet that calculate the work hours of students and faculty members, but Excel kept changing the dates and time into integers. As a result, when I needed to look up the information, everything was out of order and did not match with the original data.
-
I myself never experienced corrupting data that lead to such a chaotic mistake. However, regarding what I faced so many times, it is “Click ‘yes’ without carefully evaluating the message that says ‘do you want to remove this from the server?.” I think that is the most important mistake we should avoid because many users get annoyed when the warning message shows up. They suddenly click “yes,” even though they don’t know what the message is about. The more they click without reading, the higher risk that the data is corrupted.
-
One of the major mistakes that I usually make is not intentionally save work until it is completely finished. For me, it is hard to remember that I should always click “save” when moving toward the end. After experiencing several times of losing work, I changed my habit and get used to click “save” periodically. Those moments are suffering, but the habit I get is meaningful. An efficient and stable way of processing data and doing work is to click “save” periodically and make extra copies.
-
The mistake I’ve made was clicking “yes” without evaluating the message. Sometimes I try to finish the work quickly and then I end up clicking “yes” way too quickly so I can get done earlier. This has caused me to lose important files like essays, and excel files. I usually don’t read the directions properly which causes me to get into this situation. I also get confused sometimes by what the directions are saying but this is something that throws me off and other people as well.
-
One of the mistakes that I remembered I made before was “starting working on the database without doing a full backup first”. Sometimes I just totally concentrated on finishing my assignment with a good quality and quickly at the same time, so I just forgot to pay attention to keep my assignment in my laptop. Once my laptop was low on battery and it turned off automatically, it was so exhausted that I saw over half of my work disappeared. Therefore, I remember to click the “save” button after I make any change of my each assignment in order to avoid this thing happening again on me. Remembering to do a full backup firstly as always is a really important and necessary step for us.

I do not have much experience in sorting data. However after reading “Stupid Data Corruption Tricks,” I think the most important mistake to avoid would be “Clicking “yes” without carefully evaluating the message that says “do you want to remove this from the server?” This could happen within seconds just because you were in a rush and did not read the entire message. This results in a lot of time wasted, it would be frustrating after working on this data for an extended period of time for it all to be deleted from your device.
-
I am guilty of the “starting work without doing a full backup first” trick mentioned in the article. Whenever I get an assignment having to do with excel or tableau, I always jump right in so I can finish the assignment in as little time as possible. Now that I am working with data software more often, I understand the importance of backing up the data since there are multiple ways for me to lose all the work I’ve done.
-
Perhaps the most common mistake I make is Number 3: not doing a full backup before starting to work on data. This has gotten me in trouble many times, but one instance was for a sociology data project due the night I decided to do it. I was under so much pressure to finish, I never did a backup, and ended up messing up so many things that starting over would’ve been impossible without having a full backup handy. In the end, I never turned the assignment in, as it was horribly incorrect, and received a zero.
-
I was once working on a project into the early morning hours. I wanted to get some rest so I turned off my laptop. Not realizing that I had not only not saved my work but I hadn’t even backed up numerous files, I scowled at the screen for a good remainder of the day.
-
i made the mistake of the first place in Stupid Data Corruption which is “click Yes without reading what it is about.” There was a time when i was really tired and busy. I just want to finish my work as soon as possible. i was just finish my research paper and i though that i already save it. I turned it off and its appeared an announcement, which i was not take a look of it, called “are you sure want to delete all ?” I clicked yes without hesitate and when i realized of that stupid move. i had to write again my 10 pages research all the way from the beginning. In conclusion, this is a very stupid data corruption which will waste lots of your time and hard work.

I haven’t really worked with a database but a problem I did and might do in the future is “stating to work on a database without doing a full backup first”. This happened to me more than once, I usually write thousands of words on Word and dont save my work until I finish, and in many cases either my laptop freeze or my batter dies. This happened to my father before me when he was doing his thesis for graduate school, he worked all night writing and he lost his work and he still remember that moment. Now, I try to save my work whenever I remember and I hope I will always do in the future.
-
I have made one of the mistakes stated in the article many times. I have a tendency to start working on a database without doing a full backup first. There have been times where i have gotten away with it without anything happening, but there have also been times where something would crash or restart or accidentally close out and all of my work would be gone and i would have to start from scratch. This actually happened in our class when i was working on assignment #2.
-
I have no experience in data area, but I think the most important to avoid is that Click “yes” without carefully evaluating the message that says “do you want to remove this from the server?” I may get impatient when I see lots of datas presented, then I will finish this work as soon as possible so that I easily click the “delete” button or forgot to save the document in the computer.
-
I think the most important thing to avoid is clicking yes without reading and/or understanding the entire message that popped up. I have noticed that when working on an assignment for a good amount of time, whether it be on excel or word, sometimes the software will slow down and stop working for a few moments. The most common message that appears on the tab is “Excel Not Responding.” After this, a message with multiple options will appear. So if a user clicks the wrong option, all of their hard work can be lost.
-
I have not experience any type of data problems. I am not that experience with any data programs. I believe clicking yes without carefully evaluting the message that says “do you want to remove this from the server?” is the biggest problem. I have witness people do that. Also I believe Start working on the database without doing a full backup first is a huge issue because work can go missing if you dont.

I had made a mistake of number 3. On that time, I was helping teacher to make a statistics about the final grade of the whole class, there are hundreds of students on the list, I had to type the grade one by one. when I came to the middle of the work, there was a email, then i closed the Excel and checked email, when I back to work, I found that the grade list was empty, then I realized I didn’t click save and I didn’t have any backup. Thus, I had to finish the work from the beginning again.
-
I think that the most important mistake to avoid is starting work on the database without doing a full backup first. By forgetting to make up a backup file, you can just lose all of the progress that you made within seconds. I think it is very important to keep a backup file just in case you make a mistake and close out of the database, you can just upload the backup and continue working.
-
I have never made any of these mistakes firsthand but if I were to, the mistake I could see myself making the most is number 1. Sometimes i find myself moving too fast without paying attention to what I am reading and this would be an exact time that this problem would come back and bite me.
-
The worst mistake I have made out of this reading is not backing up my work with a save. In the past I have lost a tremendous amount of work that took considerable time by not saving and then having a computer issue or my laptop running out of battery as I forgot to charge it. Luckily now technology helps as you can use document recovery, but I definitely always remember to same my work frequently despite the new technology.
-
I have made the mistake of clicking “yes” to a message that I have not carefully read. Although i was able to backtrack and undo the mistakes, it was a tedious and time consuming process that allowed more room for error. Keeping constant attention to detail would have allowed the process of completing my assignment to be more efficient and less troublesome.
-
I find often falling victim to not backing up or saving my work before I make changes to the worksheet. Often I would accidentally delete entries or copy in the wrong set of data or formula and it would past over the data already there and i would be gone. Also I would not back up my work and then proceed to use the wrong set of data and my pier work would be gone.
-
I did in fact happen to make one of the mistakes listed in the article. I remember one time I had a paper that was due and clicked “yes” without thinking which led to my entire paper getting deleted. Thankfully I was able to reload my computer and search through my hard drive which led me to discovering a saved copy of my paper. It’s mistakes like that which could lead you to pull hair off the top of your head.
-
I would say one of the most common problems and one that I have made is clicking “Yes” before making sure that is what I want to do because I can become easily impatient.
-
There is a time that I clicked “yes” before full consideration. This is a really bad habit that do not think comprehensively before make that decision. And that time I did not save my document for my editing. So I lost some processes of my homework and I had to redo the homework from a very first draft.
-
Yes I have made one of these common mistakes; multiple times I have done assignments but forgot to save the work I did before closing the program. Most recently on Assignment 2 I finished the assignment and thought I had successfully emailed my finished assignment in for grading, but it turns out the email did not successfully deliver and all my work was lost. As a result I had to redo almost the entire assignment in a two hour period before class.
-
I do a lot of marketing, so number one is my most made mistake. I deal a lot with .csv files when it comes to email marketing. Whenever, I need to import or export mailing lists, they automatically open in Excel. Unfortunately, it comes with a lot of excess data that I don’t need! I’m not aware of any other platforms to work with, so I just do the extra work. It doesn’t take much time just tedious.
-
I have not saved a copy of a database before working on it before. it has really screwed me up. Thankfully, I could download it again from my email. Secondly, I have opened CSV directly into excel. Apparently, this is bad for large integers, but I haven’t run into such issues.
-
I enter data without having to analyze the information with formulas, so pretty much the only mistake to be made is entering a “0” when I should have entered a “1”. However, sometimes when I copy and paste, or try to drag a column down to copy into a bunch of different rows at the same time by dragging down, a message will pop up that says something like, “are you sure you want to…”. I don’t read the whole message most of the time so I don’t know what it is, which is something I will definitely try to be more conscious of incase I accidentally entered information into a cell that is already filled.
-
The mistake I usually make is that “Start working on the database without doing a full backup first.” If my friends call me to go out or something really interesting me, i always forgot i was writing an essay or doing some important work even ignore it. As a result, i should do it again. It is important that we need save it when we finish it or we have to leave for something.
-
One thing I’ve been a victim of more than once is not backing up my data before I start. My excel sheet gets shut down one way or another, and all of that data is gone forever. I feel that this backup is the most important thing to have because if your worksheet gets shut down for some reason, all of that hard work won’t have been for nothing.
-
I think that one of the most common problems, one that I use to do regularly is clicking the “yes” button before seeing that it does because I don’t feel like reading it and it is a waste of time the majority of the time. I don’t do that now because I clicked that once and it downloaded a bunch of stuff and I ended up getting a virus; lesson learned.
-
Because I work with many different application and data formats, I always accidentally open unsupported data types on Excel and vice-versa. It is very difficult to keep an eye on the file formats but it has to be done. Lately I have started organizing files with their formats together.
