A table is developed and presented to facilitate the computation of the PearsonQ 3 (“cosine method”) estimate of the tetrachoric correlation coefficient. Data are presented concerning the accuracy ofQ 3 as an estimate of the tetrachoric correlation coefficient, and it is compared with the results obtainable from the Chesire, Saffir, and Thurstone tables for the same four-fold frequency tables.
