Obtain stats from one of the following functions: To perform multiple comparisons of group means, provide the structure Test, which performs multiple comparisons against a control group. Scheffe’s procedure, Fisher’s least significant differences (LSD) method, and Dunn & Honestly significant difference criterion (default option), the Bonferroni method, Pairwise comparisons of the group means, or treatment effects. To compensate for multiple tests, you can use multiple comparison procedures. Tests incorrectly rejects the null hypothesis is 1 – 0.735 = 0.265, which is much higher Probability that the tests correctly fail to reject H 0, when If the significance level for each test is 0.05, then the Suppose also that you conduct six independent Hypothesis (H 0) is rejected when it is actually true is a small

Suppose that in a single t-test, the probability that the null This fact makes it more difficult to quantify the level of significance for T-tests use the data from the same sample, hence they are not Significant difference results might be due to large number of tests.

Performing a series of t-tests to determine which pairs of meansĪre significantly different is not recommended. Information on which group means are different. This result, however, does not provide further Rejection of the null hypothesis leads to the conclusion that Analysis of variance (ANOVA) techniques test whether a set of group means (treatmentĮffects) are equal or not.
