Spearman rank correlation is used for ordinal-level variables as it measures the degree of association between two variables based on their ranks rather than their actual values. Pearson correlation should only be used for interval or ratio-level variables. Point biserial correlation is used when one variable is dichotomous (binary) and the other variable is continuous. Phi correlation is used when both variables are dichotomous.
