Bootstrap and Traditional Standard Errors of the Point-Biserial.
Harris, Deborah J.; Kolen, Michael J.
Educational and Psychological Measurement, v48 n1 p43-51 Spr 1988
Three methods of estimating point-biserial correlation coefficient standard errors were compared: (1) assuming normality; (2) not assuming normality; and (3) bootstrapping. Although errors estimated assuming normality were biased, such estimates were less variable and easier to compute, suggesting that this might be the method of choice in some educational testing programs.
