Question: (i) Obtain appropriate diagrams and summary statistics to describe the following:

? The distribution of the three repeat measurements of grip strength of the non-dominant hand, for males only;

? The distribution of the three pairwise differences between measurements (i.e. between measurements 1 and 2, 1 and 3, and 2 and 3), for males only.

(8, 12)

Provide a short commentary to accompany your diagrams and summary statistics, which should focus on any possible tendency for grip strength to increase or decrease over the three repeat measurements.
