What is a p-value?
A p-value is the probability of observing a test statistic as extreme as the one calculated from the sample data, assuming that the null hypothesis is true.
What does a small p-value indicate?
A small p-value (typically less than 0.05) indicates strong evidence against the null hypothesis, leading to rejection of the null hypothesis.
