WebOne 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. It takes the square root of the Residual Mean Square from the ANOVA and considers that to be the pooled SD. WebWhen you ask Prism to use the FDR approach (using any of the three methods), it first computes the P values using the Fisher LSD method (if you assume sampling from Gaussian distributions) or the uncorrected Dunn's test (nonparametric). These methods do not correct for multiple comparisons. bioarrow technology

WebAn older approach, no longer offered in many statistical computing packages, is Fisher’s Protected Least Significant Difference (LSD). This is a method to compare all possible means, two at a time, as t -tests. Unlike an ordinary two-sample t -test, however, the method does rely on the experiment-wide error (the MSE). The LSD is calculated as: WebDry combustion method ... Fisher’s protected LSD means taken at alpha=0.05.
