5questionsTarget: 4/5 or better
Question 11 point

Which concept is most appropriate for this situation: You need to predict a class or class probability rather than a continuous target.

Question 21 point

Which concept is most appropriate for this situation: You need to predict a continuous numeric target and evaluate prediction error.

Question 31 point

Which concept is most appropriate for this situation: You need predicted probabilities to correspond meaningfully to observed event frequencies.

Question 41 point

Which concept is most appropriate for this situation: You need to convert probabilities into actions by selecting an operating cutoff that reflects error costs.

Question 51 point

Which concept is most appropriate for this situation: You need to apply the idea taught in “Subgroup Evaluation” and explain how its input is transformed into a valid output.
