Graphs of Win Percentages

Rather than have one giant graph with the win percentages of all 32 teams, I decided to show this data over five different sections. I categorized the teams by the standard deviation of their win percentages from 2011 to 2020. There is a fifth graph of the 49ers because that team is an outlier in win percentages. If the team has a bad year, fans can rest assured that the next year might be very different!

The standard deviations are critical when ranking teams. For example, the Colts and the Bills have average win percentages of 51.88 and 50.00. However, I would argue that the Bills are the better team because their win percentage standard deviation is a mere 13.69 compared to the Colt's 18.97.

The averages of the standard deviations for the highest, second-highest, second-lowest, and lowest are 19.61, 17.38, 15.22, and 12.09, respectively.

I did not include labels on the X-axes because I did not want the lines to be too smooshed together. Finally, there is an image of the raw data at the bottom (also in the "raw data" post).
