Chapter 2 Presenting Categorical Data

When we have a data set we wish to analyse, one of the most useful things we can do first is to present the data both numerically and graphically. This gives us a good understanding of the patterns we may expect to see further on in our analyses and helps us gain an understanding of our data.

We will now consider how to begin presenting data in a way that can make sense. We will begin by looking at frequency tables, bar charts, and pie charts, methods commonly used to make sense of categorical data.
