Abstract
Equations for combining correlation coefficients (Pearson’s r) on two or more samples are provided. These equations generally produce different values than those produced using averaging methods. The proper situations in which to use the combining or averaging methods are discussed. Data from the WAIS-R manual (Wechsler, 1981) is used as an example.
