The Spearman correlation is used when both scores are from the ordinal scale, which is a type of categorical data where values can be ranked in order but the distance between the values is not necessarily equal. It is a non-parametric measure of correlation that assesses how well the relationship between two variables can be described using a monotonic function, which means that as one variable increases, the other variable either increases or decreases in a consistent manner, but not necessarily at a constant rate. The Spearman correlation coefficient can take values between -1 and 1, with 0 indicating no correlation and values closer to -1 or 1 indicating stronger correlation.
