WebJun 9, 2024 · Our tool available at www.multipletesting.com allows choosing from the most frequently used multiple-testing correction methods, including the Bonferroni, the Holm (step-down), the Hochberg (step-up) adjustments, calculation of False Discovery Rates (FDR), and q-values. WebFeb 16, 2024 · Bonferroni Correction Calculator When you conduct a single statistical test to determine if two group means are equal, you typically compare the p-value of the test to some alpha (α) level like 0.05. If the p-value of the test is less than 0.05, you reject the null hypothesis and conclude that the group means are different.

Reject the corresponding null hypothesis and repeat step 2 until the p-value is no longer significant Advantages: Strongly controls FWER; More powerful than Bonferroni
In statistics, the Holm–Bonferroni method, also called the Holm method or Bonferroni–Holm method, is used to counteract the problem of multiple comparisons. It is intended to control the family-wise error rate (FWER) and offers a simple test uniformly more powerful than the Bonferroni … See more When considering several hypotheses, the problem of multiplicity arises: the more hypotheses are checked, the higher the probability of obtaining Type I errors (false positives).

WebThe Bonferroni correction is simple to carry out - just divide the comparison-wise error rate by k # of hypothesis tests being performed. If you're in a time crunch and need to perform a lot of hypothesis tests, the Bonferroni correction is already coded in many SAS procedures.
