For Facebook, I would export data relevant to my friends. Each row would contain information about my friends. I would have a column for: first name, last name, birthday, gender, current city, current job or school information. With this information, I could filter and/or visualize which of my friends live in Philly, or how many friends are females.

My biggest takeaway is the skills I learned using Tableau. Tableau is a very useful tool, that I now know how to use; I’m glad I get to add another skill to my resume. For future students, I would tell them that this class teaches you a lot about data, data visualizations and how to analyze data. It’s important to learn these concepts through the…[Read more]

When working with a large excel file at my internship, I double clicked to copy formulas down the rest of the rows without checking to make sure it actually filled to the bottom. I then sorted my data and noticed multiple blank cells because there were cells…[Read more]

The most important principle is the first one, simplify. When looking at a chart, graph, or any other visual, it should be clear enough to know what is going on.

The most important takeaway is how not all data is complete or representative of everything/everyone. I’ve recently used Yelp to decide on a restaurant.

I possibly could have eliminated really good restaurants because of my price…[Read more]

An example of conventional wisdom would be that same-sex couples are unfit parents. I would test this by finding same-sex couples throughout the US with kids.
