MO Marketing Officer Research & Analysis 3 — Questions and Answers
Question 1: Which sampling method ensures every member of a population has an equal chance of being selected?
- Convenience sampling
- Quota sampling
- Simple random sampling (Correct answer)
- Snowball sampling
Correct answer: Simple random sampling
Simple random sampling gives every population member an equal probability of selection, minimizing selection bias.
Question 2: A marketing officer observes a 30% open rate for email campaigns but only a 1% click-through rate. The BEST next analytical step is:
- Increase email send frequency
- Analyze subject lines since open rates are high but content isn't driving clicks (Correct answer)
- Switch to SMS marketing immediately
- Cut the email list in half
Correct answer: Analyze subject lines since open rates are high but content isn't driving clicks
High open rates with low CTR indicate the subject line is compelling but the email body or CTA is not converting — content analysis is the logical next step.
Question 3: Brand equity can BEST be measured using which combination of metrics?
- Social media followers and ad spend
- Price premium, brand awareness, and customer loyalty (Correct answer)
- Website traffic and bounce rate
- Gross margin and EBITDA
Correct answer: Price premium, brand awareness, and customer loyalty
Brand equity encompasses a price premium customers pay, how well-known the brand is, and how loyal customers are — these three metrics capture its core dimensions.
Question 4: Which type of research design is MOST appropriate for testing a causal relationship between advertising spend and sales?
- Exploratory research
- Descriptive research
- Experimental research (Correct answer)
- Ethnographic research
Correct answer: Experimental research
Experimental research manipulates one variable (advertising spend) while controlling others to establish causation with sales outcomes.
Question 5: A Pareto analysis of customer complaints reveals that 80% of issues come from 20% of product defects. How should a marketing officer use this insight?
- Redesign the entire product line immediately
- Focus resources on eliminating the 20% of defects driving most complaints (Correct answer)
- Ignore minor complaints and focus on promotions
- Increase warranty period across all products
Correct answer: Focus resources on eliminating the 20% of defects driving most complaints
The Pareto principle guides prioritization — addressing the vital few defects (20%) will resolve the majority (80%) of customer dissatisfaction most efficiently.
Question 6: Which metric measures the percentage of a target market that has been reached by a media campaign at least once?
- Frequency
- Gross Rating Points (GRP)
- Reach (Correct answer)
- Cost Per Mille (CPM)
Correct answer: Reach
Reach is the unduplicated percentage of the target audience exposed to the campaign at least once during a specified time period.
Question 7: When analyzing customer lifetime value (CLV), which inputs are ALWAYS required?
- Social media engagement and follower count
- Average purchase value, purchase frequency, and customer lifespan (Correct answer)
- Ad impressions and click-through rate
- Market share and revenue growth rate
Correct answer: Average purchase value, purchase frequency, and customer lifespan
CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan — these three variables form the core CLV calculation.
