WebFollowing one-way analysis of variance (ANOVA), you may want to explore further and compare the mean of one group with the mean of another. One way to do this is by using Fisher's Least Significant Difference (LSD) test. How the Fisher's LSD test works. The Fisher's LSD test begins like the Bonferroni multiple comparison test. WebIn LSD (no adjustment), the p-value is .126 for Clerical vs. Custodial. In Bonferroni, you can see that the p-value is now .126 × 3 = .378. (It's .379 due to rounding). This means when checking the SPSS output, you can …
