WebExample of Fisher's LSD method. For example, you are measuring the response times for memory chips. You take a sample of 25 chips from five different manufacturers. The ANOVA resulted in a p-value of 0.01, leading you to conclude that at least one of the manufacturer means is different from the others. WebI will get two complementing p-vals (e.g., 0.995 & 0.005 ). Interestingly, combining the two brings about a significant p -value in the Fisher test: p = 0.0175. This is weird because I could have chosen the exact opposite test ( μ > 0) and sampled results - and still get p = 0.0175. It's almost as if the Fisher test does not take the direction ...
