This last figure denotes the validity value at or above which 90% of all true validities lie and, consequently, the minimum value one can expect in 9 out of 10 cases.
As indicated by the operational validities reported, all ability tests demonstrate good predictive validity for overall job performance.
Our final aim was to determine whether situational and past experience question validities are moderated by job complexity.
If a study reported both dimensional validities (i.e.
According to these tables, in conditions which most closely resembled the characteristics of our meta-analytic dataset (average [r.sub.xx] = .80; average U = .84; average N = 100, K = 60; [r.sub.yy] = .40 to .80), the power of the 75% rules to detect two subpopulations with validities of .40 and .60 was around 80%.
Sagie (personal communication, 1998) according to which, in realistic settings, a corrected standard deviation of true validities equal to or exceeding .10 is indicative of the existence of moderator variables.
Table 6 presents observed validities and net validities corrected for methodological features as a function of the criterion studied, the sample analysed and the gender of participants.
The mean N-weighted validities across the criteria studied varied between .222 and .530.
Second, the number of validities is small and when the variance of population correlations is zero, the [Mathematical Expression Omitted] ratio can have a value greater than 1, which is caused by second-order sampling error (see Hunter & Schmidt, 1990).
Thus, the findings of this study correspond to the expectations of validity generalization, because the variation of validities is similar in both constant and variable settings, and the variance is explained completely by artifactual errors.
The results suggest that the use of a priori hypotheses may have been the main reason why the current study produced better validities than previous meta-analyses of personality.
Criterion-related validities of personality constructs and the effect of response distortion on those validities.
