Hypothesis, P-Values, and Alpha Levels

What does it really mean when a result is “statistically significant”? This video breaks down three ideas at the heart of hypothesis testing: the null and alternative hypotheses, the p-value, and the alpha level. It then shows how they work together to reach a conclusion. You’ll learn: What a hypothesis test is and the steps to carry one out What it means to reject (or fail to reject) the null hypothesis How to write and formulate the null (H₀) and alternative (Hₐ) hypotheses How to compare the p-value to alpha to make a decision How to state your conclusion in context, with worked examples Great for introductory statistics and AP Statistics students, or for teachers looking for a clear way to explain significance testing.
