Enter the mean square between groups and the mean square within groups into the calculator to determine the f ratio.

F Ratio Formula

The following formula is used to calculate an F ratio.

F = MBG / MWG

  • where f is the f ratio
  • MBG is the mean square between groups
  • MWG is the mean square within groups

F Ratio Definition

An f ratio is defined as the ratio between the mean square between groups and the mean square within the group.

F Ratio Example

  3. Finally, calculate the f ratio.

    Calculate the f ratio using the formula above.

FAQ

What is an F ratio?

An F ratio is a measure of variance between means of groups. Just as the formula above states it’s a ratio of the mean square between groups divided by a mean square within groups. The larger the difference the higher the ratio and the higher the variance.
