Translations:F-Scores and Accuracy/3/en

Before we can calculate the final F-score first we must calculate your individual precision and recall. When a player does a cube there are four possible outcomes for every segment in that cube: a true positive result, a false positive result, a false negative result and a true negative result. A true positive (tp) result is when a player adds a segment that should be added. A false positive (fp) is when a player adds a segment that should not be added. A false negative (fn) is when a player misses a segment they should have added. A true negative (tn) is when a player correctly leaves out a segment that does not belong. In the figure below you can see an example of false negative and of false positive.
