Power of the Independent Samples t Test under a Prevalent Psychometric Measure Distribution.
Sawilowsky, Shlomo S.; Hillman, Stephen B.
Journal of Consulting and Clinical Psychology, v60 n2 p240-43 Apr 1992
Notes that studies in psychology often have low power because of inadequate sample size and that prevalent psychometric distributions are sometimes radically nonnormal. Demonstrates robustness of independent samples t-test with respect to Type I error. Shows that researchers may use power tables based on population normality without modification for this radically nonnormal distribution. (Author/NB)
