BConclusions researchers make about the information uncovered in one study

CThe degree to which a sample represents the population of interest ✓ Correct

DThe degree to which results extend to other settings or conditions

Correct answer: (C) The degree to which a sample represents the population of interest

Explanation

Population generalizability is the degree to which a sample represents the population of interest.

Conclusions about a single random sample stop at the sample itself, not the population.

Conclusions about one study's information describe findings, not their reach to the population.

Extending results to other settings or conditions is ecological, not population, generalizability.

A representative sample is the precondition for valid population generalization.

Adequate size and random selection together raise this form of generalizability.
