The generalizability of a study increases when
A) the study is ethical
B) an experiment is used
C) debriefing is used
D) confederates are used
E) The sample is more representative of the population
The Correct Answer and Explanation is :
The correct answer is E) The sample is more representative of the population.
Explanation:
Generalizability refers to the extent to which the findings from a study can be applied to or across different populations, settings, or situations beyond the sample used in the research. When a study’s results are generalizable, it means that the conclusions can be reasonably extended to the broader population that the sample represents.
Why is representativeness important?
Generalizability increases when the sample is more representative of the population because the characteristics of the sample closely mirror those of the larger group. If the sample accurately reflects the diversity, distribution, and demographic makeup of the entire population, the study’s findings are more likely to hold true across that population.
For example, in medical research, if a study on a new treatment includes participants from different age groups, genders, ethnicities, and health statuses, the results are more likely to be applicable to the broader patient population. On the other hand, if the sample only includes a specific group, such as young males, the findings may not be generalizable to other groups, like older individuals or females.
Other Options:
- A) The study is ethical: While ethical considerations are critical to conducting a study, they do not directly impact generalizability.
- B) An experiment is used: While experiments can provide causal evidence, they don’t guarantee generalizability unless the sample is representative.
- C) Debriefing is used: Debriefing is important for ethical reasons but does not affect the generalizability of findings.
- D) Confederates are used: Confederates are typically used in controlled settings to manipulate social situations, but they do not influence the generalizability of a study.
In conclusion, a study is more generalizable when the sample reflects the broader population’s diversity, allowing for the study’s results to be applied more widely.
