Definitions:

F Value

A statistic obtained in analysis of variance (ANOVA) testing, used to determine whether the means of several groups are equal or show significant differences.

F-Tests

A group of statistical tests that compute the ratio of variances to analyze the statistical significance of the differences between means.

Nondirectional

Pertains to hypotheses or tests that do not specify a direction of effect but instead test for any difference or association.

Type II Error

The probability of accepting a null hypothesis when it is false.
