MRA Report Writing & Presentation 3 — Questions and Answers
Question 1: What does the term 'data visualization best practice' of maintaining a high data-ink ratio mean?
- Using as many colors as possible to make charts visually appealing
- Maximizing the proportion of ink devoted to actual data rather than decorative elements (Correct answer)
- Printing reports on high-quality paper
- Ensuring all charts include gridlines and borders
Correct answer: Maximizing the proportion of ink devoted to actual data rather than decorative elements
Edward Tufte's data-ink ratio principle holds that non-data ink (decorations, redundant labels) should be minimized to keep focus on the data.
Question 2: In a market research presentation, when should a researcher use a waterfall chart?
- To show the distribution of survey responses on a Likert scale
- To display how an initial value is affected by a series of positive and negative changes (Correct answer)
- To compare brand awareness across multiple demographic groups
- To map geographic sales territories
Correct answer: To display how an initial value is affected by a series of positive and negative changes
Waterfall charts are ideal for showing how sequential increases and decreases lead to a final cumulative value.
Question 3: When writing a research report, passive voice should generally be used for which section?
- Executive summary
- Recommendations
- Methodology section, to maintain scientific objectivity (Correct answer)
- Introduction stating business objectives
Correct answer: Methodology section, to maintain scientific objectivity
Methodology sections conventionally use passive voice to emphasize procedures over the researcher, maintaining scientific neutrality.
Question 4: A stacked bar chart is most appropriate when the researcher wants to show:
- Correlation between two continuous variables
- Both the total magnitude and the composition breakdown across categories (Correct answer)
- Trends over time for a single metric
- Statistical significance between two group means
Correct answer: Both the total magnitude and the composition breakdown across categories
Stacked bars allow simultaneous comparison of totals and segment proportions across categories.
Question 5: Which of the following is considered a critical flaw when presenting Net Promoter Score (NPS) data in a report?
- Reporting the NPS alongside sample size
- Comparing NPS scores across different industries without noting they are not directly comparable (Correct answer)
- Displaying both promoter and detractor percentages
- Noting the confidence interval around the NPS
Correct answer: Comparing NPS scores across different industries without noting they are not directly comparable
NPS benchmarks vary significantly by industry, so cross-industry comparisons without this context are misleading.
Question 6: What is the recommended maximum number of bullet points per slide in a research presentation to maintain audience comprehension?
- 10–12 bullets to ensure completeness
- 3–5 bullets to avoid cognitive overload (Correct answer)
- No bullets; only images should be used
- As many as needed to cover the topic exhaustively
Correct answer: 3–5 bullets to avoid cognitive overload
Cognitive load research supports limiting bullets to 3–5 per slide so audiences can absorb and retain information.
Question 7: When reporting qualitative findings, which technique best maintains rigor while making results accessible to clients?
- Reporting only the most extreme or dramatic quotes
- Using representative verbatim quotes linked to identified themes with frequency context (Correct answer)
- Summarizing all responses in aggregate percentages
- Presenting raw transcripts without analysis
Correct answer: Using representative verbatim quotes linked to identified themes with frequency context
Pairing illustrative quotes with thematic context and frequency signals balances authenticity with analytical rigor.
