I think the most important takeaway from this course for me is how to work with data-based programs. I have rudimentary knowledge in Microsoft, but this course is the first I have heard of Tableau, Hadoop, Piktochart and et cetera. Because it is inevitable that I will work with data in my future career, I think it is important to have a run down…[Read more]

A data driven service I normally use is LinkedIn. If I were to store the data on LinkedIn on a spreadsheet, the rows will be the names of my connections. Some of the columns can be what jobs they are currently working and for what company, their majors in college, their interests/hobbies, whether they are a primary or a secondary connection in…[Read more]

This article is interesting because it partly answers the question of why the field of data processing have not managed to make much impact despite the coverage Big Data is currently getting, and correlates well with the information we have been given…[Read more]

I use KPI in managing my social and academic activities. There are set numbers of homework and social events on campus every week, which is specific and measurable because I can calculate how much work I do or how many events I go per week. It is achievable because I can adjust social events attendance according to my workload and vice versa in…[Read more]

I have tried to open CSV files in Excel for the first assignment in this class – the result was a mix of mistakes #6 and #9. The data were all messed up and compressed together because of the tiny allocated space in a typical cell, phone numbers and coordinates were auto-corrected to integers and because there was no data dictionary, neither the…[Read more]

This article is interesting because it shows how much of a gray area data privacy is. Cyberlaw is a fairly recent area of the law, and it shows. This is why data is such a controversy every time it is brought to court – nobody knows what to do about it. Yet the consequences are…[Read more]

In my opinion, the most important principle is having an appropriate response. While the internet has made it very easy to spread information gleaned from data globally, because there is too much to take in, a piece of information can just as easily be lost among terabytes of raw data. As for using search engines, unless the searcher knows what…[Read more]

I think the most important thing about last discussion is how easy it is to fake trustworthiness. It might take a while, but when just putting up a profile photo that might not even be real makes the user/reviewer’s words a little more reliable, there is no telling what a dedicated liar can accomplish. Of course, most people don’t have the time…[Read more]

The dataset I found was MyPyramid Food from http://catalog.data.gov/dataset/mypyramid-food-raw-data-f9ed6, which I found interesting because it catalogs information not only on amount of calories and fat in commonly eaten food but also provides insight on ‘extras’. From this dataset, I can learn how many calories most types of food have and…[Read more]

This article is interesting because it points out how data is now the new question mark for the accounting departments and corporations as a whole. Data is an asset that could amount to trillions in value; it can be depreciated, exchanged and used to make…[Read more]

A piece of conventional wisdom I have heard is that ‘You can get a higher paying job if you have a college degree’. To test the validity of this statement, I would collect data on current workers’ earnings and whether they have a college degree or not. The responses would be separated into two categories: those who answered ‘Have a college degree’…[Read more]
