WebbThe rank-biserial correlation coefficient, rrb , is used for dichotomous nominal data vs rankings (ordinal). The formula is usually expressed as rrb = 2 • ( Y1 - Y0 )/ n , where n is the number of data pairs, and Y0 and Y1 , again, are the Y score means for data pairs with an x score of 0 and 1, respectively. These Y scores are ranks.
