p-Value

A p-value is the probability of obtaining results at least as extreme as the observed results, assuming the null hypothesis is true.

In practical terms:

  • Small p-value (typically < 0.05): The observed data is unlikely under the null hypothesis, so you reject the null hypothesis
  • Large p-value: The observed data is consistent with the null hypothesis, so you fail to reject it

If the p-value is less than or equal to the decision criteria, we can reject the null hypothesis in favor of the alternative.
