Quizplus · Accepted Answer

The point-biserial correlation should be used to measure the relationship between gender (a dichotomous variable) and grade point average (a continuous variable) for a group of college students. Pearson correlation would be appropriate if both variables were continuous, Spearman correlation would be appropriate if both were ordinal, and phi-coefficient would be appropriate if both were dichotomous.
