Statistical investigation • Carry out investigations of phenomena, using the statistical enquiry cycle: – conducting experiments using experimental design principles, conducting surveys, and using existing data sets; – finding, using, and assessing appropriate models (including linear regression for bivariate data and additive models for timeseries data), seeking explanations, and making predictions; – using informed contextual knowledge, exploratory data analysis, and statistical inference; – communicating fi ndings and evaluating all stages of the cycle. • Make inferences from surveys and experiments: – determining estimates and confi dence intervals for means, proportions, and differences, recognising the relevance of the central limit theorem; – using methods such as resampling or randomisation to assess the strength of evidence.
