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.
