Data may have a rich structure, but we first concentrate on the simplest data
structure, a single numerical measurement from each 'individual' in a group.
The exercises in this chapter will help you to learn about:
- Graphical displays — stem and leaf plots, dot plots, box plots and histograms
- Numerical summaries of centre and spread — means, medians and standard deviations
- Proportions and percentiles
- Linear and nonlinear transformations
