Exercise

White wine tasting

Not all variables are normally distributed! Here we display histograms of white wine ratings for each of the same four countries. They were generated using the code in the editor on the right, which is nearly identical to the code that you used to plot the red wine scores. If you struggled with the previous exercise, take your time with this one to understand everything before moving on.

Instructions

100 XP
  • Look at the four histograms. None of these have the typical bell-shaped distribution that the histograms in the previous exercise displayed. Take a moment to think about what may be causing this difference.
  • Press "Submit Answer" when you understand the code in the console and the resulting histograms.
