     B) The maximum number of participants needed for the study
     C) The final stage of data analysis when all themes have been identified
     D) The amount of data collected from each participant

 

374. In an exercise science study, what does “longitudinal” design involve?
     A) Collecting data at one point in time
     B) Comparing different populations or groups at a single point in time
     C) Following participants over a long period to observe changes and trends
     D) Using a large sample of participants to gather extensive data in a short period

 

375. What is “ethical approval” in exercise science research?
     A) The process of ensuring that the study’s results are valid and reliable
     B) The process of obtaining consent from participants to participate in a study
     C) The process of ensuring that the research design adheres to ethical principles, protecting participants’ rights and welfare
     D) The process of confirming that the study’s hypothesis is scientifically sound

 

376. What is a “cohort study” in exercise science research?
     A) A study where participants are randomly assigned to different experimental conditions
     B) A study that examines a specific group of people over time to identify factors that contribute to health outcomes
     C) A study that tests a specific exercise regimen on participants
     D) A study that looks at one-time data collection to examine a hypothesis

 

377. In exercise science, what is the “double-blind” method?
     A) A method where only the researchers are unaware of which group receives the intervention
     B) A method where both the participants and the researchers are unaware of the treatment group assignments
     C) A method used to evaluate the external validity of the study
     D) A method that uses a placebo to test the effectiveness of an intervention

 

378. What is the purpose of “pilot testing” in exercise science research?
     A) To test the long-term effects of an exercise intervention
