When is the F1 score useful?

Answer and explanation

Correct answer: To evaluate the balance between precision and recall

The F1 score is the harmonic mean of precision and recall, so it combines both measures into one value. It is useful when both false positives and false negatives matter, especially in classification tasks with imbalanced classes. It measures predictive classification performance, not execution time or file properties.
