A health infographic gives percentages but not the total sample size. What limitation does this create?

Answer and explanation

Correct answer: It becomes difficult to judge the reliability of the data

The governing concept is context-aware data interpretation. A percentage describes a proportion, but its practical meaning depends on the base or total sample. For example, 50% of 10 people and 50% of 10,000 people do not provide the same strength of evidence. Without the sample size, judging reliability and significance is difficult, so option A is correct. The other choices are unrelated design effects.
