Definitions:

Test Statistic

A calculated value from sample data, used in statistical hypothesis testing to determine whether to reject the null hypothesis.

Random Samples

A subset of individuals chosen from a larger set, where each individual has an equal chance of being selected.

Rejected

In statistical analysis, refers to the decision to discard the null hypothesis based on the evidence from sample data and the predetermined significance level.

F-distribution

A continuous probability distribution that arises in the analysis of variances for comparing sample variances, used in ANOVA tests.
