A graph shows only percentages but not the total number of students. What information may remain hidden?

Answer and explanation

Correct answer: The actual sample size

The governing concept is careful interpretation of quantitative visualizations. A percentage describes a proportion, but its practical meaning depends on the total or denominator. For example, 50% could represent 5 of 10 students or 500 of 1,000 students; the percentage is identical, but the sample size and strength of the conclusion differ. Therefore, option C is correct. The other choices are visual or geographic details, not missing statistical context.
