If an F ratio is ______ the critical value, I will ______ the null hypothesis and conclude that ______.

A) greater than; not reject; the groups are not all equal to each other
B) greater than; reject; all of the groups are different from each other
C) less than; not reject; the groups do not differ significantly from each other
D) less than; reject; the groups are all equal to each other

F Ratio

A statistic used in analysis of variance (ANOVA) to determine whether the means of several groups are equal.

Null Hypothesis

A statement suggesting that there is no significant effect or difference, or that a parameter equals a specific value, used as a basis for statistical testing.

Critical Value

A value on the test statistic scale that marks the threshold for rejecting the null hypothesis, distinguishing between significant and insignificant outcomes.
