Overview

Bivariate data analysis introduces students to some methods for identifying, analysing and describing associations between pairs of variables, including using the least-squares method as a tool for modelling and analysing linear associations. Students will develop proficiency to conduct regression analysis, with the aid of a CAS calculator. We will help students to effectively communicate results and make predictions using appropriate terminology.
