The Pearson r “correlation coefficient” is a summary statistic that indicates both the strength and direction of the relationship between two variables It has a value of between ‐1 and +1 – Values less than zero (e.g ‐0.8) indicate a negative correlation

Understanding the Pearson Correlation Coefficient (r) The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales).

Compute the Pearson . r. between one of your dichotomous variables and one of your continuous variables. This . r. is a . point biserial. correlation coefficient. Using the usual formula for computing the . t. to test the null hypothesis that rho is zero, test the null hypothesis that the point biserial correlation coefficient has a value of ...
