WebBonferroni: adjust the α used to assess 'significance' such that α n e w = α o k Dunn-Sidak: adjust α using α n e w = 1 − ( 1 − α o) 1 / k (Note that the Dunn-Sidak assumes all the tests within the set are independent of each other and could yield familywise type I error inflation if that assumption does not hold.) WebSPSS multiplies the p-value of the least significant differences (LSD) by the number of tests, and produce a new p-value. There are three categories, totally 3 possible pair-wise comparisons.

WebThe second time, you set it to 1% level. If a particular comparison is statistically significant by the first calculations (5% significance level) but is not for the second (1% significance level), its adjusted P value must be between 0.01 and 0.05, say 0.0323. A separate adjusted P value is computed for each comparison in a family of comparisons.
