We finally created a bar chart for our data. Remember that our main goal was visualizing the distribution of the pattern variable. Below you can see your plot from the previous exercise. It will help you answer these familiar questions:

  1. How many patterns of alcohol consumption are defined by the WHO?
  2. How many countries fit into each pattern?
  3. Is the distribution of patterns dominated by one category? Or are all pattern categories equally distributed?
  4. If the distribution is dominated by one category, which one is the most frequent?
