calculate the coefficient of determination, 𝑟^2, and interpret in the context of the association being modelled and use the model to make predictions, being aware of the problem of extrapolation
U3.AoS1.24
determine the equation of the least squares line giving the coefficients correct to a required number of decimal places or significant figures as specified, and distinguish between correlation and causation
U3.AoS1.25
use the least squares line of best fit to model and analyse the linear association between two numerical variables and interpret the model in the context of the association being modelled
