Filtering summarized output
In the last exercise, you may have noticed that the country that voted least frequently, Zanzibar, had only 2 votes in the entire dataset. You certainly can't make any substantial conclusions based on that data!
Typically in a progressive analysis, when you find that a few of your observations have very little data while others have plenty, you set some threshold to filter them out.
