In April, I set out to do weekly analysis on different data sets. I successfully did so. There are my four analyses:

• First, I looked at the poll trends for the Democratic primary.
• Second, I looked at “endorsement points” for the Democratic candidates.
• Third, I looked at Trump’s approval rating over time.
• Fourth, I looked at the accuracy of FiveThirtyEight’s predictions.

It was a fun month and I learned a lot.
