1. What sampling method or plan was used by the authors in this study?
   Simple random sampling
   Systematic sampling
   Convenience sampling
   Network sampling
2. According to Grove & Gray (2019), what are the potential biases of this sampling method?
   This is a strong probability sampling method with very little potential for bias.
   This method is used when an ordered list of all members of the population are available and provides a random but not equal chance for inclusion in the study.
   This method provides little opportunity to control for bias because subjects are included in the study merely because they happen to be in the right place at the right time.
   This method is specific to the individuals who were recruited and the information gained cannot be generalized to others who don't share these types of experiences.
   None of the above biases best describe the sampling method chosen by the author.
3. What was the final sample size reported by the authors for this study?
   2,010 participants
   2,419 participants
   1,506 participants
   504 participants
4. Was a power analysis conducted? If so, which statement best describes the results of the power analysis?
   The authors mention that a power analysis was conducted using a power of 0.8, an alpha value of 0.05, and a moderate effect size of 0.30.
   The authors mention that a priori power analysis was conducted, and 1500 subjects were determined to be needed for the study.
   The authors do not report that a power analysis was conducted.
5. Which of these statements would be considered to be a specific inclusion criterion for the sample in the research article?
