WebFinding significance in a one-way ANOVA F test means there is strong evidence that not all population means are equal. Which are different? We can explore ... WebApr 19, 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 …
