Section 1: Foundations of Analytics & Problem-Solving (20 Questions)
**Question 1.**
Which of the following best defines "analytics" in a business context?
A) The process of collecting raw data without any specific purpose
B) The process of developing actionable decisions or recommendations
based on insights generated from historical data
C) The use of intuition and gut feelings to make business decisions
D) The process of storing data in large warehouses for future use
**Answer:** B
**Rationale:** Analytics combines computer technology, management
science techniques, and statistics to solve real problems by generating
actionable insights from data. Options A, C, and D describe data
collection, intuition, and storage respectively—not analytics.
---
**Question 2.**
A manager uses trial and error, relies on common sense, and seeks a
"good enough" solution rather than the optimal one. This approach is
best described as:
A) Analytics
B) Heuristics
,3|Page
C) Prescriptive analytics
D) Machine learning
**Answer:** B
**Rationale:** Heuristics involves learning by acting, using trial and
error, valuing experience, relying on common sense, and seeking
satisficing (good enough) solutions. It is fast and frugal but may lead to
decision biases. Analytics (A) uses step-by-step procedures and seeks
optimal solutions.
---
**Question 3.**
Which type of analytics answers the question "What happened?" by
creating summaries of historical data?
A) Predictive analytics
B) Prescriptive analytics
C) Descriptive analytics
D) Diagnostic analytics
**Answer:** C
**Rationale:** Descriptive analytics is the preliminary stage of data
processing that creates summaries of historical data to answer "What
, 4|Page
happened?" or "What is happening?" using standard reporting,
dashboards, and visual analytics.
---
**Question 4.**
A data scientist uses historical data and machine learning algorithms to
forecast next month's sales. This is an example of:
A) Descriptive analytics
B) Diagnostic analytics
C) Predictive analytics
D) Prescriptive analytics
**Answer:** C
**Rationale:** Predictive analytics uses data, statistical algorithms, and
machine learning to identify the likelihood of future outcomes based on
historical data, answering "What will happen next?".
---
**Question 5.**
Which analytics approach answers "What should be done about it?" by
providing optimal decisions based on predicted scenarios?
