Question 1.
What is the formula for Recall?
Show hintHide hint
Think about how we measure true positives against total positives.
Question 2.
If a model has 60 True Positives and 20 False Negatives, what is its Recall?
Show hintHide hint
Use the Recall formula, substituting the values.
3Question 3.
What does Recall measure in a classification model?
- False Positives
- True Positives
- True Positive Rate
Show hintHide hint
Recall focuses on correctly identifying actual positives.
4Question 4.
True or False: A high Recall value means few False Negatives.
- True
- False
Show hintHide hint
Think about the implications of Recall in identifying positives.
Question 5.
Given a dataset of 200 cases with 80 True Positives, 5 False Negatives, and 15 False Positives. Calculate the Recall and discuss its adequacy in a healthcare setting.
Show hintHide hint
Use the formula and think about the importance of Recall in critical applications.
Question 6.
A model shows TP = 40, FN = 10, and FP = 5 with 100 actual cases. Calculate Recall and suggest strategies to improve it.
