Statistical investigation
S7-1: Carry out investigations of phenomena, using the statistical enquiry cycle:
- conducting surveys that require random sampling techniques, conducting experiments, and using existing data sets;
- evaluating the choice of measures for variables and the sampling and data collection methods used;
- using relevant contextual knowledge, exploratory data analysis, and statistical inference.

- recognising the effect of sample size on the variability of an estimate.
