Dixon's Q test for outlier identification

It covers the test's methodology, its common application in fields like chemistry, and important criticisms regarding its assumptions and proper use. The content includes a step-by-step implementation guide and the author's perspective on cautiously using the test for outlier identification rather than automatic removal.
