Model
A simplified or idealised description of a situation. The term model is used in two different ways in the curriculum.
In the probability thread, the use of “models of all the outcomes” refers to a list of all possible outcomes of a situation involving elements of chance and, at more advanced levels, a list of all possible outcomes and the corresponding probability for each outcome.
At level 8 in the statistical investigation thread, an achievement objective refers to “appropriate models (including linear regression for bivariate data and additive models for time-series data)." Used in this way, a model is an idealised description of the underlying system the data was taken from, and the model is intended to match the data closely.
