The Spearman correlation coefficient uses ranked data to measure the strength and direction of the association between two variables, unlike the Pearson correlation coefficient, which requires interval or ratio scale data. Both can ascertain the strength of a relationship and produce values between -1 and 1, and significance testing can be applied to both types of correlation coefficients.
