In this 2-week unit students are provided opportunities to:
- represent probabilities of outcomes of chance experiments using fractions, decimals and percentages, comparing predicted outcomes with observed results
- describe, interpret and pose questions about data presented in tables, column graphs, line graphs and timelines
- investigate how data representations can be misleading or biased.
