What are some potential advantages of comparison group designs?
What will be an ideal response?
While attempting to minimize threats to internal validity is an essential task when designing comparison group studies, comparison group designs may have advantages for external validity. External validity refers to the ability to generalize the program effect estimate beyond the units in the study to the broader target population of individuals or units eligible to participate in the program. Comparison group designs do not generally require that participation in the program group be restricted or controlled to meet the inherent requirements of the design itself. This is not always the case with the designs discussed next (in Chapter 8), such as the randomized control design, that have fewer threats to internal validity but may have to be implemented with only a selected subset of the program population, e.g., individuals willing to volunteer to participate in random assignment.
