Statistical investigation and sampling
Identify and classify sampling methods, evaluate survey questions for flaws, and assess whether a sample is representative of the population.
Displaying data
Classify variables as categorical or numerical, construct frequency tables and histograms, describe the shape of a distribution, and identify misleading features in statistical graphs.
Measures of centre and spread
Calculate the mean, median and mode of a dataset, compute the population standard deviation, and choose the most appropriate measure of centre for a given context.
Quartiles, box plots and outliers
Find quartiles and the interquartile range from ordered data, construct five-number summaries, identify outliers using fences, and interpret parallel box plots.
