In statistical analysis of binary classification, the F-score or F-measure is a measure of a test's accuracy. It is calculated from the precision and recall of the test, where the precision is the number of true positive results divided by the number of all positive results, including those not identified correctly, and the recall is the number of true positive results divided by the number of all sampl… Webarithmetic, geometric or harmonic means is somewhere between the 90% and 100% mark, with arithmetic being the highest, the harmonic mean more conservative, and the arithmetically weighted average Accuracy is at the minimum.
