Which factor most influences whether a statistic is representative of the population?

• A. Font choice used in the report
• B. Sampling method
• C. Chart color
• D. Publication date

Answer: (B)

Representativeness hinges on how the sample is chosen. If the sampling method gives every member of the population a fair chance to be included and reflects the population’s makeup (for example, using random selection or stratified sampling to match subgroups), the resulting statistic will closely mirror the true population parameter. Conversely, if the sample is selected in a biased way—favoring certain groups or convenient respondents—the statistic will not represent the whole population well.

Aesthetics like font choice or chart color don’t affect who was included in the sample, so they don’t influence representativeness. Publication date affects timeliness or relevance but not how accurately the sample reflects the population.
