“…The literature that is most frequently referred to (Howell, 1999;Kenny, Kashy, & Bolger, 1998;Keppel, 1991) deals mostly with common nonparametric tests but not with complex issues, like interactions, leaving researchers confronted with a conundrum. Two reviews support this assumption: Sherman, Buddie, Dragan, End, and Finney (1999) analyzed all publications within 20 years in the Personality and Social Psychology Bulletin (PSPB) whereas Stone-Romero, Weaver, and Glenar (1995) analyzed the Journal of Applied Psychology (JAP). Fifteen percents of all studies in PSPB and less than height in JAP used nonparametric tests.…”
