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 … See more The name F-measure is believed to be named after a different F function in Van Rijsbergen's book, when introduced to the Fourth Message Understanding Conference (MUC-4, 1992).

Pairwise Alignment. Pairwise sequence alignment is the type of sequence alignment that involves aligning two sequences to identify the optimal pairing of the sequences. It is based on a scoring system that assigns positive scores to matching characters and negative scores to mismatching characters or gaps.

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.”.
