WebAdjusted P values are very different than Fisher's LSD P values. Note the huge difference: Adjusted P values correct for multiple comparisons; Fishers LSD test does not. The "exact" P values computed by the two methods, therefore, will give very different results and must be interpreted very differently. WebInstead you should use McNemar's test. If you want to compare an observe distribution of values with a distribution expected by theory, do not use a contingency table. Prism offers another analysis for that purpose. 3. Analyze. From the data table, click on the toolbar, and choose Chi-square (and Fisher's exact) test.
