Suggested answer to exercise: Alcohol consumption from the 2005 questionnaire, 1

Question 1: Where are the mode, the lower tail and the upper tail of this distribution?

Suggested answer

The upper tail of the distribution is long, streching from about 25 units/week to above 50. The mode is at the extreme left of the distibution. As we can see from the exercise Variables from the 2005 M.Sc. Questionnaire, zero was the most frequent observation. As a result, there is no lower tail for this distribution.

This is how they appear on the histogram:
