SECTION I: QUANTITATIVE ANALYSIS METHODS
(Questions 1–20)
1. Which statement best defines quantitative analysis?
A) Analysis using subjective opinions and personal intuition
B) Analysis using objective numerical data to identify patterns and support
business decisions
C) Analysis focusing solely on qualitative customer feedback
D) Analysis examining only historical trends without numbers
Correct Answer: B
Rationale: Quantitative analysis relies on measurable, objective data and
statistical methods to uncover patterns and relationships, providing
,evidence for business decisions. It contrasts with qualitative analysis, which
uses subjective information such as opinions and attitudes .
2. What is the first step in the eight-step decision-making model?
A) Generate alternatives
B) Identify the problem
C) Establish decision criteria
D) Evaluate alternatives
Correct Answer: B
Rationale: The decision-making process begins with identifying the problem
or opportunity. Only after the problem is clearly defined can alternatives be
generated and evaluated .
3. Which of the following is an example of qualitative analysis?
A) Calculating the break-even point
B) Conducting a survey with open-ended responses
C) Computing the mean of a dataset
D) Solving a linear programming model
Correct Answer: B
Rationale: Qualitative analysis uses subjective data such as opinions,
attributes, and open-ended survey responses. Break-even analysis, mean
calculation, and linear programming are quantitative methods .
4. Which of the following is a quantitative analysis method?
, A) Brainstorming sessions
B) Subjective judgments
C) Linear regression
D) Rankings based on favorites
Correct Answer: C
Rationale: Linear regression is a quantitative method that uses numerical
data to analyze relationships between variables. Brainstorming, subjective
judgments, and personal rankings are qualitative methods .
5. A company wants to determine how many units it must sell to cover all
costs. Which quantitative method should be used?
A) Decision tree analysis
B) Break-even analysis
C) ANOVA
D) Network diagram
Correct Answer: B
Rationale: Break-even analysis calculates the sales volume at which total
revenue equals total costs, resulting in zero profit. It is the appropriate tool
for determining cost coverage .
6. Which of the following best describes the purpose of a decision tree?
A) To compare variations between groups
B) To analyze graphs and trends
C) To map out decisions and their possible consequences under
uncertainty
D) To measure the strength of a linear relationship
Correct Answer: C
