9.7 | From Guinness to Clinical Trials: The Story of T-Distribution | Medical Software Course
Description
Ever wondered where the t-distribution came from? In this lesson, we conclude our exploration of statistical significance by delving into the fascinating history of the t-distribution, born out of the Guinness Brewery. We then transition to its crucial role in modern clinical trials, explaining power analysis, type I and type II errors, and the importance of sample size. Finally, we discuss critical caveats and common misinterpretations of statistical significance and p-values.
