Quizplus · Accepted Answer

Spearman's rho is more suitable when the measurement scale is ordinal, meaning data can be ranked but not necessarily quantified. Pearson's r is more applicable when the measurement scale is interval or ratio, meaning there is a quantifiable distance between measurements. Categorical data does not involve numerical values, making neither statistic suitable.
