Q. In which scenario is the F1 Score particularly useful?
A.
When false positives are more critical than false negatives
B.
When false negatives are more critical than false positives
C.
When the class distribution is balanced
D.
When the class distribution is imbalanced
Solution
F1 Score is useful in imbalanced class distributions as it balances precision and recall.
Correct Answer:
D
— When the class distribution is imbalanced
Q. In which scenario would you prioritize recall over precision?
A.
When false positives are more costly than false negatives
B.
When false negatives are more costly than false positives
C.
When the dataset is balanced
D.
When you need a high overall accuracy
Solution
In scenarios where missing a positive case (false negative) is more critical, such as in medical diagnoses, recall should be prioritized over precision.
Correct Answer:
B
— When false negatives are more costly than false positives
Q. What is the main limitation of using accuracy as a metric?
A.
It does not account for class imbalance
B.
It is difficult to calculate
C.
It only applies to binary classification
D.
It requires a large dataset
Solution
Accuracy can be misleading in imbalanced datasets, as it may give a false sense of model performance by not reflecting the true predictive power for minority classes.
Correct Answer:
A
— It does not account for class imbalance
F1 Score is the harmonic mean of precision and recall, making it a better metric for imbalanced datasets where one class is more significant than the other.
