Infographic Design Research & Evidence-Based Practice 4

Question 1

Which axis manipulation technique makes a small difference appear dramatic in an infographic chart?

Accepted Answer

Truncating the Y-axis to start above zero

Answer

Truncating the Y-axis exaggerates visual differences between values, making minor variations look large and misleading viewers about the actual magnitude of change.

Question 2

In evidence hierarchy, where do systematic reviews and meta-analyses rank?

Accepted Answer

At the top, as the strongest form of synthesized evidence

Answer

Systematic reviews synthesize all available high-quality research on a topic, and meta-analyses statistically combine results, making them the highest tier of evidence.

Question 3

What is 'cherry-picking' in the context of infographic data selection?

Accepted Answer

Selecting only data points that support a predetermined conclusion while ignoring contradictory evidence

Answer

Cherry-picking distorts the overall picture by presenting a favorable subset of data as representative of the whole, which misleads viewers.

Question 4

A researcher reports p < 0.05 in a study cited by an infographic. What does this indicate?

Accepted Answer

There is less than a 5% probability the results occurred by chance

Answer

A p-value below 0.05 means statistical significance — the probability of observing these results by random chance alone is less than 5%.

Question 5

When an infographic presents a '40% increase,' what additional context is MOST critical for accurate interpretation?

Accepted Answer

The baseline value from which the increase is calculated

Answer

A 40% increase from a base of 10 equals 4 units, while 40% from a base of 1,000 equals 400 units — without the baseline, the statistic is meaningless.
