Thus, we can proceed to perform Fisher’s least significant difference test to determine which group means are different. Using values from the output of the ANOVA, we can calculate Fisher’s test statistic as: LSD = t.025, DFw * √ MS W (1/n 1 + 1/n 1) LSD = t.025, 27 * √ 36.948*(1/10 + 1/10) LSD = 2.052 * √ 7.3896; LSD = 5.578 WebOct 24, 2014 · How to calculate Fisher's LSD from ANOVA output.
