Quizplus · Accepted Answer

The Spearman rank order correlation is used to measure the correlation between two sets of ordinal data. It is appropriate when the variables being compared are ranked in either ascending or descending order. It is not appropriate for nominal data, which has no inherent order, or for interval or ratio data, which have equal intervals between measurements and a true zero point. Therefore, option B is the best choice.
