What is a key factor when considering the external validity of research findings?

• A. Methodological rigor
• B. Representation of the sample population
• C. Timeliness of data collection
• D. Availability of funding

Answer: (B)

The representation of the sample population is a key factor when considering the external validity of research findings because it directly influences the extent to which the results can be generalized to a larger population. External validity refers to the applicability of research findings beyond the specific conditions or population studied. If the sample is not representative of the broader population, the results may not be valid or applicable to that larger group. A well-chosen sample that reflects the diversity of the population allows researchers to draw broader conclusions and increases the confidence that the findings can be applied in real-world settings. Methodological rigor, while important for ensuring that the study is well-designed and the findings are trustworthy, primarily pertains to internal validity. Timeliness of data collection can impact the relevance of the research but does not directly affect external validity. Availability of funding affects the scope and scale of the study but is not inherently tied to whether the sample adequately represents the target population. Thus, focusing on how well the sample represents the population is crucial for assessing the broader applicability of research findings.
