WebApr 2, 2024 · F1 Score considers both precision and recall. It is the harmonic mean (average) of the precision and recall. F1 Score is best if there is some sort of balance between precision (p) & recall (r) in the system. Oppositely F1 Score isn’t so high if one measure is improved at the expense of the other. For example, if P is 1 & R is 0, F1 … WebHi Omkar, the F-test in ANOVA is testing to determine whether the means are different. So, the more different the means are, the stronger the evidence. A different way to state “the more different the means are” is “a higher variance amongst the group means.”.
