Question

The F-ratio increases as _________. the variability between means increases relative to the variability within groups the variability between means decreases relative to the variability within groups the total variability increases the total variability decreases

Answer 1

Answer: variability between means increases relative to the variability within groups

Explanation:

The formula to calculate F-ratio : variance between groups divided by variance within groups

Here, F-ratio
`\propto` is proportional to variance between groups but inversely proportional to variance within groups .

So, F-ratio increases when variability between means increases relative to the variability within groups.
