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.

S7-2: Make inferences from surveys and experiments:

• making informal predictions, interpolations, and extrapolations
• using sample statistics to make point estimates of population parameters
• recognising the effect of sample size on the variability of an estimate.

Probability

S7-4: Investigate situations that involve elements of chance:

• calculating probabilities, using such tools as two-way tables, tree diagrams, simulations, and technology.
