12.2.1 - Hypothesis Testing. In testing the statistical significance of the relationship between two quantitative variables we will use the five step hypothesis testing procedure: 1. Check assumptions and write hypotheses. In order to use Pearson's r both variables must be quantitative and the relationship between x and y must be linear.
