Alissa Smith, Eugene Seto, Jake Montana, and I are working together for Assignment 4. Our project will show how and why salaries for players in the MLB have changed over time. We will also compare the salaries of the players by league and by team.

I believe that the most important takeaway from this course is to recognize how much data we interact with on a daily basis. It is also important to understand how data analysis leads to decision making which impacts our lives. This course showed me how important data is in our world today. I also learned about different ways to analyze and…[Read more]

A data driven service that I frequently use would be Spotify. There are many different playlists available on Spotify that contain a number of songs. Data from Spotify could be stored using a spreadsheet similar to the one we created during the In-Class Exercise 11.1 that we completed on Wednesday. The columns could be listed as Playlist, Song,…[Read more]

This article uses four data visualizations to prove that primary turnout does not have any impact on the general election. In 2016 primary elections, the Republican turnout is up and the Democratic turnout is down. The article says that voter turnout is an…[Read more]

A KPI that I use daily is the amount of time I spend exercising each week. It is specific and measurable because there are certain exercises I do each day for a certain number of minutes. It is achievable because I can work to achieve whatever goals I set for myself each week. It is relevant because it helps me stay in shape and makes me healthier…[Read more]

I have made one of these mistakes in the past. I have clicked “yes” without carefully evaluating the message that says “do you want to remove this from the server?” I was working on an assignment when I did that and it deleted some of the data that I needed. Thankfully, I noticed the mistake towards the end of the assignment. I did it because I…[Read more]

Although I know virtually nothing about operas and am not very interested in them, this article caught my attention. I found it interesting that the same four operas were being performed over and over again. This article discusses how the Metropolitan Opera will…[Read more]

I believe that the most important principle from the Hoven article is to ask why. Many people may be content with just visualizing the data in front of them. However, it is crucial that people understand what the data means. The only way to do that is to ask why the data is how it is. Once we understand why the data is how it is, we can begin to…[Read more]

The most important takeaway from last weeks discussion was how bias can make many reviews unreliable. The reviews are often unreliable because many people write a really positive review or a really negative review based on one experience. You can’t really decide how a your experience at a restaurant will be based off another person’s only time at…[Read more]

One dataset I found was the United States’ Trade Overview for 2013. I found this on data.gov. I found this interesting because it showed how much the U.S. trades, who we trade with, and what that trade does for the United States. I learned that the total imports and exports in the U.S. have increased in almost every year since 1990. I also learned…[Read more]

An example of conventional wisdom could be, “if you work hard you will succeed.” This is an idea that is generally accepted by most people because it makes sense that the harder someone works, the better chances that person has of succeeding. One way that this could be tested is by comparing how successful students who study are versus the success…[Read more]
