Statistics & Probability
Data and chance are all around us. In this topic, you’ll explore how to collect and display data, calculate averages and spread, and understand how likely things are to happen.
Concepts
Build your confidence with data and probability by learning to summarise information, describe variation, and make informed predictions. These lessons include hands-on investigations and support you to think critically about chance and data.
Statistical Investigations
Plan and carry out investigations using the PPDAC cycle: Problem, Plan, Data, Analysis, Conclusion.
Data Displays
Use bar graphs, dot plots, and stem-and-leaf plots to summarise data.
Measures of Centre and Spread
Find and interpret the mean, median, mode, and range of a dataset.
Probability
Use fractions, decimals, and percentages to describe likelihood and compare probabilities.
