Read the note: 'Limitations affecting validity and generalizability' What is the primary issue addressed?

• A. Limitations that improve external validity.
• B. Limitations affecting validity and generalizability.
• C. Limitations requiring no future work.
• D. Limitations that verify all results.

Answer: (B)

The key idea is limitations that affect validity and generalizability. Validity is about how accurately a study measures what it intends to measure and draws correct conclusions. Generalizability, or external validity, is about whether those conclusions apply beyond the specific study setting, sample, or conditions. When a note highlights limitations, it points to aspects that could threaten both the accuracy of the findings and their applicability to other contexts—things like design flaws, measurement error, small or unrepresentative samples, or biases. So the primary issue addressed is how these limitations might undermine the trustworthiness of the results and their ability to generalize. The other options don’t fit because they imply effects or goals that aren’t typical of study limitations: improving external validity, eliminating need for further work, or claiming that all results are verified.
