It is assumed that in Years F-6, students have had many learning experiences involving choosing and identifying questions or issues from everyday life and familiar situations, planning statistical investigations and collecting or accessing data. It is assumed that students are now familiar with categorical, count and measurement data, have had learning experiences in recording, classifying and exploring individual datasets of each type, and have seen and used tables, picture graphs and column graphs for categorical data and count data with a small number of different counts treated as categories, and dotplots of measurement and count data. It is assumed that focus in exploration and comment on measurement and count data has been on each set of data by itself, but that in Year 6, students have become familiar with considering more than one set of categorical data on the same subjects. In doing so, they met the concept of statistical variables and understood that they were investigating data on pairs of categorical variables. For example, if data are collected on students’ favourite TV show and favourite holiday activity, then in Year 6, the combination of data on TV shows and holiday activities are explored together using two-way tables and side-by-side column graphs.
