Key Concepts

P-value

The P-value represents the probability of obtaining test results at least as extreme as the ones observed, assuming that the null hypothesis is true. It provides a measure of the evidence against the null hypothesis; a lower P-value indicates stronger evidence against it.

Significance Level

The significance level, denoted as alpha (?), is a threshold set before conducting a hypothesis test. It defines the maximum acceptable probability of committing a Type I error, which is the error of rejecting a true null hypothesis. Common choices for ? include 0.05 and 0.10.

Hypothesis Testing Decision Rule

The hypothesis testing decision rule compares the P-value to the chosen significance level. If the P-value is less than or equal to the significance level, the null hypothesis is rejected, meaning the observed data are unlikely under the null hypothesis. If the P-value is greater than the significance level, there is insufficient evidence to reject the null hypothesis.

Null Hypothesis

The null hypothesis is a default statement or hypothesis that there is no effect, difference, or relationship among the variables being tested. It serves as the starting point for statistical testing and is assumed to be true unless the evidence provided by the data leads to its rejection.
