So far we have only looked at methods of analysing linear associations and not non-linear associations. Luckily, linearization provides a convenient way of transforming non-linear associations into linear ones so that they can be analysed using the same methods.

Linearization works by applying a transformation of some form to either the explanatory and/or response variables datasets. In Further Maths, you will only deal with situations requiring one of the datasets to be transformed at a time.

Keep in mind that the formula for the linearised model must include the transformation (e.g. the formula for a model which has undergone a square transformation to the explanatory variable will be of the form y=a+bx^2).
