As part of his study on athletic ability, Dr. Shah invites participants to his lab where he has simulated a basketball court. He concluded that participants who made more baskets were more athletic than participants who did not. Which of the following is true if Dr. Shah's study has LOW external validity?

a) The study's findings are likely to generalize to real-life basketball games.
b) The study's findings may not apply to real-life basketball situations.
c) The study's results are highly reliable and valid.
d) The study's participants were selected randomly from the population.

Final answer:

If Dr. Shah's study on athletic ability has low external validity, the findings may not apply to real-life basketball situations. Low external validity means that the results are less likely to reflect behaviors and abilities outside the laboratory setting. The correct option is A

Step-by-step explanation:

If Dr. Shah's study on athletic ability has low external validity, b) The study's findings may not apply to real-life basketball situations. External validity refers to how well the results of a study generalize to or inform us about people, times, places, and contexts that were not studied. When a study has low external validity, the results are less likely to reflect what would occur outside the laboratory or in different conditions.

The concept of external validity is crucial when interpreting the findings of any study. Sociological and psychological studies often aim to understand human behaviors and tendencies and to apply these findings to the broader population (generalizability). Therefore, research in these fields should be carefully designed to ensure both reliability and validity. Validity is particularly important as it ensures the study measures what it is supposed to measure accurately.

It is important for researchers to consider various elements that could potentially affect external validity. These include participant characteristics, the environment in which data is collected, and the situational context. For instance, a simulated environment might not capture all factors present in a natural setting, such as spectator pressure, physical condition of the players, or environmental variables that could affect performance. In addition, the action of making baskets, while indicative of certain athletic abilities, may not encompass all aspects of athleticism such as endurance, strength, teamwork, or strategy. Consequently, conclusions drawn solely from basket-making ability about overall athletic skill might miss other critical elements.

When it comes to interpreting experimental findings, researchers must also conduct statistical analysis to determine the significance of their results. This helps in distinguishing whether differences observed in the study could have occurred by chance or whether they are statistically significant. Meaningful differences generally imply that there is a less than five percent chance that the observed results occurred if there was no actual difference between the groups.

In the context of Dr. Shah's study, if the findings indeed have low external validity, caution must be used before extending the implications of the experiment to realms outside the laboratory. Understanding the limitations of a study's design and accurately interpreting its results are essential steps in scientific inquiry, regardless of the subject being studied, whether it's an issue of athletic ability or any other area of research.
