Explain the threats to external validity and when they might exist in a research study.

Question

Quizplus · Accepted Answer

The Answer is Threats to external validity refer to factors that may limit the generalizability of research findings to other populations, settings, or times. These threats can exist in a research study when certain conditions or circumstances are present.

One common threat to external validity is the use of a non-representative sample. If the participants in a study do not accurately reflect the larger population of interest, then the findings may not be applicable to that population as a whole. This can occur when researchers use convenience samples or when certain groups are underrepresented in the sample.

Another threat to external validity is the artificiality of the research setting. If the study is conducted in a controlled laboratory environment that does not accurately mimic real-world conditions, then the findings may not be generalizable to real-world situations. This can be a concern in experimental research where the manipulation of variables may not occur in natural settings.

Additionally, the timing of the study can also impact external validity. If the research is conducted during a specific time period or under certain conditions that are not representative of other times or circumstances, then the findings may not be applicable beyond that specific context.

Overall, threats to external validity can exist in a research study when the sample is not representative, the research setting is artificial, or the timing of the study is limited. Researchers must be mindful of these potential threats and take steps to minimize their impact in order to ensure the generalizability of their findings.
