http://changingminds.org/explanations/research/analysis/f-ratio.htm WebThe F ratio is then calculated as: If the average difference between groups is similar to that within groups, the F ratio is about 1. As the average difference between groups becomes greater than that within groups, the F ratio becomes larger than 1. WebF-statistics are the ratio of two variances that are approximately the same value when the null hypothesis is true, which yields F-statistics near 1. We looked at the two different variances used in a one-way ANOVA F-test. Now, let’s put them together to see which combinations produce low and high F-statistics. city journal media bias fact check
