Infographic Design Research & Evidence-Based Practice 2

Question 1

Which sampling method is MOST appropriate when you need to represent proportional subgroups within a population for infographic data?

Accepted Answer

Stratified random sampling

Answer

Stratified random sampling divides the population into subgroups and samples proportionally from each, ensuring all segments are represented accurately.

Question 2

When citing a statistic in an infographic, what is the PRIMARY reason to include the year the data was collected?

Accepted Answer

To allow viewers to assess data currency and relevance

Answer

Including the data collection year lets viewers judge whether the information is still current and applicable to present-day contexts.

Question 3

A designer wants to show that ice cream sales and drowning incidents both rise in summer. Which logical fallacy must they warn viewers about?

Accepted Answer

Correlation does not imply causation

Answer

Both variables share a common cause (hot weather), so presenting them together without context implies a causal link that doesn't exist.

Question 4

What does 'triangulation' mean in the context of evidence-based infographic research?

Accepted Answer

Verifying findings with three or more independent sources

Answer

Triangulation strengthens credibility by cross-checking a claim against multiple independent data sources or research methods.

Question 5

An infographic claims '9 out of 10 dentists recommend this toothpaste.' What critical piece of information is missing?

Accepted Answer

The sample size and how dentists were selected

Answer

Without knowing the sample size and selection method, the statistic could reflect a tiny, non-representative group rather than a meaningful consensus.
