Question

A researcher wants to assess the relationship between the number of training sessions dogs have before a dog show, and whether or not they win a prize at the dog show. Which correlation should the researcher use to measure the relationship?

Point-biserial correlation

Spearman’s rho

Cramer’s phi

Pearson’s correlation

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
