How Is A P-Value Defined In Statistics?

Описание: Ever wondered what a p-value truly represents in the world of statistics? This video breaks down the fundamental definition of a p-value, helping you grasp its core concept and significance in hypothesis testing.

In this video, you'll learn:
► The precise definition of a p-value as the probability of observing data as extreme as, or more extreme than, the observed data, assuming the null hypothesis is true.
► How p-values are used to assess the strength of evidence against a null hypothesis in statistical inference.
► The common threshold (alpha level) of 0.05 and what it signifies for rejecting or failing to reject the null hypothesis.
► That a small p-value suggests strong evidence against the null hypothesis, while a large p-value indicates insufficient evidence to reject it.
