Exploring chance and data

Gathering, reporting and interpreting data. Making predictions and testing and reporting predictions

Home » Numeracy Focus Areas » Exploring chance and data

General overview

This focus involves learners explore chance events and working with data in authentic contexts.

For chance, learners at early levels consider the likelihood of everyday events such as weather phenomena occurring. They make predictions about the likelihood of single events occurring, understanding the nature of fairness, and comparing the probabilities of multiple events at upper levels.

For data, learners at early levels move from interpreting and presenting simple data displays, to gathering, reporting and interpreting data from their experiences.

At upper levels, students critically evaluate media and public-body data and statistics, including examining and explaining distributions and making conjectures about trends they may observe in the data.

Key ideas and language include understanding the random nature of naturally occurring events; the likelihood of an event or its expected outcome, and the variability in samples and populations.

Making conjectures about what learners expect to find, and then testing and reporting on these predictions are critical elements of understanding chance and data.
