Discussion 1: group research designs | SOCW 6301 – Social Work Practice Research I | Walden University
The generalizability of findings from a study, or external validity as it is also called, refers the degree to which they can be used in other settings and populations. Although I am a language teacher, I don’t have access to any specific research, I can discuss some concerns regarding the external validity.
Sample selection can limit the generalizability of a research study. If the study’s sample is not representative of the larger population, the results may not be generalizable. It may be impossible to generalize findings from a particular study if it only included participants of a certain geographical area or age group.
Another aspect of research design that can limit generalizability is the study’s method of data collection. The findings could not be generalized if the method of data collection isn’t standardized and reliable. If the data is self-reported, for example, it’s possible that participants will provide incorrect or incomplete information.
Additionally, the study’s research design and methods might limit generalizability if they are too artificial or controlled. If a lab study is done, then the results might not translate to other situations. If variables are manipulated in a manner that does not represent how they naturally happen, then the results may not generalize.
In summary, there are several aspects of research design that can limit the generalizability of a study’s findings, including sample selection, data collection methods, and the artificiality of the research design itself. When designing and interpreting studies, researchers must take into account these factors to make sure that the results accurately represent the target population.
