    Q1. A researcher concludes that a new medication is effective based on a study with a low dropout rate. What is the potential flaw in this argument?

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

    Answer: The low dropout rate may have biased the results
