Level 3 · Mathematics M3.7

Statistics and chance

Collect and show data, find averages, and measure how likely things are.

Write a clear survey question, group the answers and draw bar charts and pie charts. Then find the mean, median, mode and range, compare two groups, and spot a chart that misleads. The last three chapters measure chance on a scale from 0 to 1, work out chances, and test them with coins and dice.

For parents and teachers

For learners who can draw a bar chart from a frequency table and who know what a fraction like 3/4 means. In many schools this fits children of about 11 to 13, and older learners who never met statistics can start here too. Each chapter takes one or two short sessions. A learner can work alone: every exercise has its answer and the reason for it. Each chapter also has a short page for the adult, with three questions to ask.
