F1 Score
Understanding the Answer
Let's break down why this is correct
The F1 Score is a single number that shows how well a model balances catching true positives (precision) and finding all positives (recall). Other options are incorrect because Error Rate tells you how many predictions are wrong, but it does not combine precision and recall; Precision measures only how many of the predicted positives are correct.
