WebFor example, here we have the second most extreme table we could possibly obtain, and our p-value is 26%. That's a consequence of a, the discreteness, and b, demanding a demanding a exact test. It is what it is. so the Fisher's exact test doesn't distinguish between rows and the columns, transpose the table, you get the same p value out. 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. importance of exegesis
