Precision or Positive Predictive Value is a measure for exactness and Recall or Sensitivity is a measure of completeness. They range from 0 to 1 and the best possible value for both of them is 1.
Precision = TruePositive / (TruePositive + FalsePositive)
Recall = TruePositive / (TruePositive + FalseNegative)
