Missing Data

In honor of the Super Bowl yesterday, Steve Hayward of Power Line posts the following potentially misleading chart. It looks at NFL players' contributions to the two major political parties. 

It shows the percentage of those contributing to each party. Big advantage in donors to Republicans, but the few Democrats gave more each, on average.


What you don't learn from the chart is what percentage made political contributions. It might be true that most players don't. You could get charts like these if only 20 players contributed and 19 of them gave to Republicans, interesting maybe but not significant. 

If most players give to political parties, it means something, but we have no idea of what percentage do.
