Categorical Data
This worksheet helps students build their understanding of the two types of categorical data, through definitions, examples and questions.
This resource is part of a larger unit designed for Year 6 that helps students develop their understanding of the different types of statistical variables they are likely to encounter during statistical investigations at this level.

Learning goals
- We are learning to interpret and compare the four types of data sets (ordinal, nominal, discrete, continuous) using comparative displays and determining the range, mode (frequency) and shape of data in graphs, dot plots and bar charts.
- We are learning to interpret and compare data displays, including side-by-side column graphs, tables and diagrams for two categories (e.g. age, height) and compare the usefulness of each display for data interpretation.
