What Is P-Value in Statistics?

Pickl AI

Summary: The p-value is a crucial statistical measure that quantifies the strength of evidence against the null hypothesis in hypothesis testing. A smaller p-value indicates stronger evidence for rejecting the null hypothesis, guiding researchers in making informed decisions. How P-Value is Used in Hypothesis Testing?
