What is the Bonferroni Correction & How does it work?

The Bonferroni correction is a simple yet powerful method for controlling the family‑wise error rate when multiple statistical tests are performed.

It works by dividing the desired overall significance level (Ξ±) by the number of independent comparisons (m), producing a stricter threshold for each individual test.

\alpha_{adj}=\frac{\alpha}{m}
Ξ±_adj = adjusted significance level

When the corrected Ξ± is applied, the probability of obtaining at least one false‑positive result across all tests does not exceed the original Ξ±, making the conclusions more reliable.

Frequently Asked Questions
What is the Bonferroni correction?
The Bonferroni correction adjusts the significance level for each test when multiple comparisons are made to reduce the chance of false positives.
How do I use the Bonferroni correction calculator?
Enter your desired overall significance level and the number of tests, then click calculate to get the adjusted significance level.
Why is the Bonferroni correction important?
It helps control the family-wise error rate, reducing the likelihood of making one or more Type I errors when conducting multiple hypothesis tests.
What does Ξ±_adj represent in the Bonferroni correction?
Ξ±_adj is the adjusted significance level for each individual test after applying the Bonferroni correction.
Can I use the Bonferroni correction for any type of statistical test?
Yes, it can be applied to various types of tests as long as they are independent comparisons.
What is the downside of using the Bonferroni correction?
It increases the risk of Type II errors (false negatives) by making individual tests more stringent.
How does the Bonferroni correction affect power in hypothesis testing?
It can reduce statistical power because it makes it harder to detect true effects due to the stricter significance threshold.
