In this unit, based on the survey instrument and data used in the Census At School: New Zealand project, students learn about the notion of a distribution, and compare distributions of different variables. Several relevant Level 7 Achievement Objectives are addressed in this unit.

This unit involves students formulating questions about data sets, displaying and analysing data as well as reporting their conclusions. Information about the pregnancies of 56 woman and their newborn babies is used as a context.

In this unit students look at the components of time series. They compare sets of data using displays, use associated vocabulary and determine appropriate statistics. They interpret their results and draw conclusions. From given sets of data and other information they predict population figures.
