3.6 Interpreting graphs

A study of Weddell seals (Bryden et al. 1984) measured, among other things, body length. A histogram of the body length of \(90\) female seals is shown in Fig. 3.2.

  1. Describe this histogram in words (average; variation; shape; outliers).
  2. What alternative graphical displays could be used to display these data?
  3. Critique the graph.
