Whenever the F-ratio is near 1.00 it means that
A)a mistake has been made in the computation.
B)there are large systematic effects present.
C)the experimental manipulation probably had the predicted effects.
D)the between-groups variation is no larger than would be expected by chance alone and no larger than the within groups variance.

Quizplus · Accepted Answer

The F-ratio is calculated by dividing the variance between groups by the variance within groups. When it is close to 1.0, it means that the between-group variation is not significantly larger than the within-group variation, which suggests that the experimental manipulation did not have a significant effect. This is not a mistake in computation but rather a result of the analysis. Therefore, choice D is the correct answer.
