AO1: Plan and conduct surveys and experiments using the statistical enquiry cycle: determining appropriate variables and measures; considering sources of variation; gathering and cleaning data; using multiple displays, and re-categorising data to find patterns, variations, relationships, and trends in multivariate data sets; comparing sample distributions visually, using measures of centre, spread, and proportion; presenting a report of findings.

In this unit students investigate the different ways data varies over time looking at variables that fluctuate randomly, those that steadily increase or decrease and those that show seasonable behaviour. They display data, use appropriate vocabulary and determine appropriate statistics. Students choose a time series and, working in groups, formulate questions about the data they have collected and report back their findings.

A graphics calculator or spreadsheet would be useful here to help analyse the data.

In this unit students investigate small amounts of discrete data. They look at how changes in data affect calculated statistics. Building on what they have learnt, students solve a problem in context from a set of given data.

This unit is based on the survey instrument and data used in the Census At School: New Zealand project. The survey and the data are on the website: http://www.censusatschool.org.nz/. In this unit students will become familiar with the site, generate random samples of data, and compare data using box and whisker plots.

This unit develops statistical literacy exploring multivariate data sets that have been created by the students and from the CensusAtschool (NZ) and CensusAtschool (International) sites.

This unit gives survey experience by providing students with the opportunity to design, collect and analyse data on the use of their time.

In this unit students construct, administer and analyse a survey to consider what is a typical Year 8 student.
