The Spearman rank correlation coefficient is used to determine if a relationship exits between two variables when:
A)one of the variables is ordinal.
B)both of the variables are ordinal.
C)both variables are interval and the normality requirement is not satisfied.
D)All of these choices are true.

The Spearman rank correlation coefficient is a non-parametric measure of correlation, meaning it can be used when the data does not meet the normal distribution requirements. It is appropriate for use when at least one of the variables is ordinal, when both variables are ordinal, or when both variables are interval/ratio but do not meet the normality assumption. Therefore, all the given choices are situations where the Spearman rank correlation coefficient could be appropriately applied.
