What are the strengths of the switching-replications design with respect to threats to internal validity and why does it have these strengths?
What will be an ideal response?
In randomized experiments, especially when the groups are aware of each other, there is the potential for social threats to internal validity; compensatory rivalry, compensatory equalization, and resentful demoralization are all likely to be present in educational contexts where programs are given to some students and not to others. The switching-replications design helps lessen these threats because it ensures that everyone will eventually get the program. Additionally, it allocates who gets the program first in the fairest possible manner, through the lottery of random assignment.
