Which factor is established to serve explicitly as a reference against populations that can be compared and act indirectly as an ideal achievable target by all groups?

Which factor is established to serve explicitly as a reference against populations that can be compared and act indirectly as an ideal achievable target by all groups?

• A. Distribution group
• B. Comparison group
• C. Subpopulation group
• D. Socially important group

Answer: (B)

The key idea is using a comparison group as the reference point for evaluating differences and setting a shared target. This group provides a concrete baseline against which other populations can be measured, making disparities visible and giving all groups a plausible, achievable standard to aim for. By comparing outcomes to the reference group, researchers can assess how far other groups are from a known benchmark and track progress toward equity. The other terms don’t serve that benchmarking role: a distribution group describes how data are spread, not a baseline for comparison; a subpopulation group is simply a subset within the population, not a universal reference; a socially important group reflects value or emphasis, not a methodological standard for comparison.
