Section 1: Data Analytics Lifecycle & Problem Framing (Q1-10)
Q1. Which of the following lists the six phases of the CRISP-DM framework in the
correct sequential order?
A. Data Preparation, Modeling, Business Understanding, Data Understanding,
Evaluation, Deployment B. Business Understanding, Data Understanding, Data
Preparation, Modeling, Evaluation, Deployment C. Business Understanding, Data
Understanding, Data Preparation, Modeling, Evaluation, Deployment [CORRECT] D.
Modeling, Evaluation, Business Understanding, Data Understanding, Data
Preparation, Deployment
Rationale: CRISP-DM follows a logical progression from defining the business
problem (Business Understanding) through data exploration, preparation, model
building, validation, and finally operationalizing the solution (Deployment).
Correct Answer: C
Q2. A retail company wants to reduce customer churn. The analytics team is
tasked with translating this business question into an analytical question. Which
of the following best represents a properly framed analytical question?
A. How can we improve customer service training? B. Which customer demographic
segments have the highest profitability? C. What predictive factors identify customers
with the highest probability of churning within the next 90 days? [CORRECT] D.
Should we increase our marketing budget?
Rationale: An analytical question must be specific, measurable, and data-driven;
option C translates the business goal into a predictive modeling problem with a
defined outcome and timeframe.
Correct Answer: C

Q3. During a predictive modeling project, the analytics team discovers that the
initial model performs poorly on new data. According to the CRISP-DM
framework, which phase should they revisit?
A. Deployment only B. Evaluation only C. Any previous phase, as CRISP-DM is
iterative [CORRECT] D. Business Understanding only
Rationale: CRISP-DM is an iterative cycle; poor model performance may require
revisiting Data Preparation, Data Understanding, or even Business Understanding to
refine requirements.
Correct Answer: C
Q4. A hospital's analytics team is developing a readmission prediction model.
Which stakeholder group should be consulted during the Business Understanding
phase to ensure the analytical objectives align with clinical workflow constraints?
A. Database administrators only B. Frontline nurses, physicians, and case managers
[CORRECT] C. Patients' family members only D. External competitors
Rationale: Frontline clinical staff provide essential domain knowledge about workflow
constraints, data availability, and actionable decision points for readmission
interventions.
Correct Answer: B
Q5. A manufacturing firm defines success for its supply chain optimization project
as "reduce excess inventory by 15% within six months while maintaining 99%
order fulfillment." This statement best represents which project component?
A. Data requirement specification B. Success criteria and KPIs [CORRECT] C.
Statistical methodology selection D. Data governance policy
, 3
Rationale: Success criteria define measurable targets (15% reduction, 99% fulfillment)
and KPIs that align the analytical project with business outcomes.
Correct Answer: B
Q6. An e-commerce company wants to build a recommendation engine. During
the Data Requirements step, which of the following is the most critical
specification?
A. The programming language for the dashboard B. The types of data needed
(customer demographics, purchase history, product attributes) and their sources
[CORRECT] C. The color scheme for visualizations D. The CEO's preferred statistical
software
Rationale: Data requirements specify what data is needed, where it resides, its quality,
and accessibility—foundational elements before any modeling can occur.
Correct Answer: B
Q7. A financial services firm is building a credit risk model. Which of the following
best defines the analytical objective for this project?
A. Increase the IT department's headcount B. Predict the probability of loan default
using applicant financial and behavioral data [CORRECT] C. Replace all loan officers
with automation D. Reduce the number of data sources
Rationale: The analytical objective translates the business need (managing credit risk)
into a specific predictive task with defined inputs and outputs.
Correct Answer: B
Q8. Which CRISP-DM phase involves integrating the analytical model into
operational systems and establishing monitoring procedures?
