Week 3: Scrubbing and Analysis

Lecture

Today we will be talking about a necessary evil when it comes to working with data, cleaning it. Unfortunately, if you are relying on someone else collecting the data for you, its usually not in the right format that you need it in and there might be some data points that are incorrect. Once you have scrubbed your data then you can go on to analysis. We will be talking about many tools you can use to analyze your data, but ultimately you should use what you are most comfortable with. During this analysis process we will be visualizing the data for insight only. No need to worry about design at this stage.

Decide on a topic to research around the midterm elections for your midterm. Find at least two datasets based on that topic, analyze it and visualize for insight. Be prepared to discuss your findings next week.

Example: If you are interested in climate change legislation you can look at data around its cause and effect, i.e. temperature data, extreme weather, carbon emissions, methane emissions, extinction rates, government environmental policies and see if there is any correlation.
