Suggested answer to exercise: Height from the 2005 questionnaire, 3

Question 3. Where are the mode, the lower tail and the upper tail of this distribution?

Suggested answer

The mode is the value of the variable at highest part of the graph, the region of highest frequency. This is where height is between 160 and 165 cm. The lower tail is the part of the distribution where there are relatively few observations and these are small. This is where the height is below 155 cm. The upper tail is the part of the distribution where there are relatively few observations and these are large. This is where the height is above 175 cm.

This is how they look on the histogram:
