Question 14
Content Domain 2: Exploratory Data AnalysisDuring data preparation for modeling, a team discovers a problem in the dataset that could negatively affect model performance. What should the team do next within the scope of this task?
Correct answer: C
Explanation
When issues are found during data preparation, the appropriate action is to identify mitigation strategies that reduce their impact before modeling proceeds. — Source material: "Identify mitigation strategies."
Why each option is right or wrong
A. Ignore the issue and continue directly to model training
The task calls for identifying mitigation strategies when a problem is found during preparation.
B. Replace the preparation step by selecting a final algorithm immediately
Algorithm selection is different from addressing a discovered data problem during preparation.
C. Identify mitigation strategies to address the discovered problem
The source material for Task 2.1 explicitly states "Identify mitigation strategies." In this scenario, the team has found a dataset problem during preparation, so the required next step is to identify mitigation strategies that address that issue before proceeding.
D. Assume the issue will disappear after deployment and document nothing
The task requires addressing the problem during preparation rather than postponing it to deployment.
