Spearman's test is a nonparametric method used to determine the strength of the relationship between two variables. It measures the correlation between the ranks of the two variables, rather than the actual values. This makes it suitable for data that do not meet the assumptions of parametric tests, such as normality and equal variances. In addition, it can detect non-linear relationships between variables.
