- K1 Understand and use the terms population and sample; use samples to make informal inferences about the population; understand and use sampling techniques including simple random sampling and opportunity sampling; select or critique sampling techniques in context, including understanding that different samples can lead to different conclusions about the population.
Statistical sampling
- L1 Interpret diagrams for single-variable data, including understanding that area in a histogram represents frequency; connect to probability distributions.
Single-variable data diagrams
- L2 Interpret scatter diagrams and regression lines for bivariate data, including recognition of scatter diagrams with distinct sections of the population; understand informal interpretation of correlation; understand that correlation does not imply causation; calculations involving regression lines are excluded.

- L3 Interpret measures of central tendency and variation, extending to standard deviation; calculate standard deviation, including from summary statistics.
Central tendency and variation
- L4 Recognise and interpret possible outliers in data sets and statistical diagrams; select or critique data presentation techniques in context; clean data including dealing with missing data, errors and outliers.
