Lastly, calculate its F-measure.

Correct Answer: 0.92

F-measure = (2 * Recall * Precision) / (Recall + Presision) = (2 * 0.95 * 0.91) / (0.91 + 0.95) = 0.92. It is difficult to compare two models with low precision and high recall or vice versa. So to make them comparable, we use F-Score. F-score helps to measure Recall and Precision at the same time.
