If you have data with repeated measures in both factors, Prism uses methods from Chapter 12 of Maxwell and Delaney (2) If you do not assume sphericity, Prism uses the the Greenhouse-Geisser correction and calculates epsilon. 4 Prism computes repeated-measures two-way ANOVA calculations using the standard method explained especially well in Glantz and Slinker (1). Without repeated measures, there are no choices available on the second (RM Analysis) tab. Since the data do not have repeated measures, don't check either option on the first tab.
