Quizplus · Accepted Answer

When dealing with multi-valued between-subjects variables that are measured on an interval scale, the most common method of analysis is Pearson correlation. This would allow us to determine if there is a linear relationship between the two variables. Spearman rank-order correlation, point-biserial correlation, and nonparametric correlation may be more appropriate for other types of data or variable measurement scales.
