  1. Question 1

    Q1. A researcher concludes that a new treatment is effective based on a study with a high response rate. What is the potential flaw in this argument?

    • A) The study was not randomized
    • B) The sample size was too small
    • C) The high response rate may have biased the results
    • D) The study did not control for confounding variables

    Answer: The high response rate may have biased the results

    Explanation: High response rate affects external validity. The high response rate may have biased the results is correct because it matches what the question requires. USAT, HAT and MDCAT analytical sections repeat this pattern.
