Khan Academy: Chi Square Statistic for Hypothesis Testing

You can bet on Bayes. Continuing from the previous video, scholars learn about Bayesian statistics and hypothesis testing. The 25th installment of the Crash Course Statistics series applies these concepts to continuous data and to...

Introduce the concept of hypothesis testing, confidence intervals, and degrees of freedom with a short video that also covers the chi-square test and works through several examples to help viewers understand the material.

Video gives example of hypothesis testing with an example related to medical testing. Includes setting up a null hypothesis and an alternative hypothesis. [11:26]
