Which activity in analytics problem framing defines the acceptable trade-off between false positives and false negatives?
Answer: Setting the decision threshold based on business costs
The decision threshold should be chosen based on the relative cost of false positives versus false negatives for the specific business context.
When a business problem involves optimizing delivery routes across many possible combinations, the MOST appropriate methodology is:
Answer: Operations research / combinatorial optimization
Route optimization is a combinatorial problem best addressed by operations research techniques such as linear programming or heuristic methods.
A target variable with three unordered categories (e.g., product tier: Bronze, Silver, Gold) should be modeled using:
Answer: Multinomial logistic regression
Multinomial logistic regression handles multi-class categorical outcomes with no inherent order.
Which bias occurs when a model is evaluated only on the data used to select it, inflating apparent performance?
Answer: Leakage bias
Leakage (or data snooping) occurs when information from the evaluation set influences model selection, making performance estimates overly optimistic.
Which CAP concept requires an analyst to document assumptions made during analytics problem formulation?
Answer: Model transparency
Model transparency requires documenting all assumptions so stakeholders can assess validity and reproducibility.
An analyst frames a problem as predicting revenue for the next 12 months using historical monthly data. This is best described as a:
Answer: Time-series forecasting problem
Predicting a continuous metric (revenue) over sequential time periods is a time-series forecasting problem.
