Instruction

We have the first draft of our alcohol consumption histogram. The intervals were automatically chosen by ggplot.

Check the problem

Let's see if we can find answers to the specific questions we asked earlier:

  • What was the lowest amount of per-capita alcohol consumption in 2010? What was the highest?
  • Is there one very frequent value? Is there a narrow range of frequent values? Or do all values appear equally often?
  • If there is one value or range of values that is very frequent, what is it?
  • How many countries consume more than 14 liters of alcohol per person per year?
