What does F mean in statistics?
The F-statistic is the test statistic for F-tests. In general, an F-statistic is a ratio of two quantities that are expected to be roughly equal under the null hypothesis, which produces an F-statistic of approximately 1. In order to reject the null hypothesis that the group means are equal, we need a high F-value.
