Answer to Question 1

The median salary would be more useful. Explanations will vary. Possible answer: In the case of salaries, there are
likely to be a few extreme values - salaries that are much higher than the majority of salaries. Unlike the mean, the
median is resistant to extreme values - it will not be affected by a few unusually high salaries. The median gives a
better indication of the typical salary than the mean.

Answer to Question 2

C
