Question

a strong study establishes validity because it is important that researchers

apply the research findings in a way that benefits the research population.
conduct research in an ethical manner.
generalize to a broader population.
measure what they intend to measure.

Explanation:

In research, validity refers to the extent to which a study measures what it is intended to measure. Let's analyze each option:

• "Apply the research findings in a way that benefits the research population" is about application of findings, not validity.
• "Conduct research in an ethical manner" relates to research ethics, not validity.
• "Generalize to a broader population" is about generalizability (external validity is part of it, but the core of validity is about measuring the intended construct).
• "Measure what they intend to measure" directly defines validity.

Answer:

D. measure what they intend to measure.
