Question

What statistical test should a researcher use if the researcher is examining the relation between two scale variables?

a. Mann-Whitney U test

b. Pearson correlation

c. independent-samples t test

d. chi-square test for independence

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.
