Abstract
An empirical study of the corrections for restriction
in range due to explicit selection resulted in
the following conclusions. (1) The corrected sample
correlation was no more accurate than the uncorrected
sample correlation for low unrestricted population
correlations in the range .10 to .25. (2) For
large unrestricted population correlations in the
range .60 to .80, the corrected sample correlation
was always more accurate than the uncorrected
sample correlation. (3) For moderate (.30 to .55)
unrestricted population correlations, the corrected
sample correlation was typically more accurate than
the uncorrected sample correlation. (4) The correction
was very sensitive to moderate departures
from linearity but was quite robust in the face of
rather substantial departures from homoscedasticity.
