How to Use Fisher’s Least Significant Difference (LSD) in R
Web19 apr. 2024 · We can use the following code to create this dataset and perform a one-way ANOVA on it in R: Since the p-value in the ANOVA table (.0188) is less than .05, we can conclude that not all of the mean exam scores between the three groups are equal. Thus, we can proceed to perform Fisher’s LSD test to determine which group means are different. Web12 apr. 2024 · To perform this test, we first calculate the following test statistic: LSD = t.025, DFw * √MSW(1/n1 + 1/n1) where: t.025, DFw: The t-critical value from the t-distribution table with α = .025 and DFw is the degrees of freedom within groups from the ANOVA table. MSW: The mean squares within groups from the ANOVA table.
