Quizplus · Accepted Answer

When both sets of measures are in ordinal form, the appropriate correlational technique should be the Spearman r. This is because the Spearman r is a nonparametric measure of association that does not assume a linear relationship between variables and can handle ordinal data. The Pearson r requires interval or ratio level data and assumes a linear relationship between variables. The t test is a method for comparing means between two groups and is not appropriate for correlational analysis. The coefficient of determination is a measure of the proportion of variability in a dependent variable that is explained by an independent variable, but it is not a correlational technique.
