On the Mean and Variance of the Tetrachoric Correlation Coefficient

Brown, Morton B.; Benedetti, Jacqueline K.

Psychometrika, 42, 3, 347-55, Sep 77

Estimates of the mean and standard deviation of the tetrachoric correlation are compared with their expected values in several two by two tables. Significant bias in the mean is found when the minimum cell frequency is less than five. Three formulas for the standard deviation are discussed. (Author/JKS)
