=Consider random assignment in experiments. Using three of the seven confounds of internal validity, explain how they benefit from random assignment.
What will be an ideal response?
May vary. Possible examples include: Selection, where the selection of subjects
results in biases – random assignment would eliminate this; Statistical regression,
where extremes eventually regress to the mean – random assignment would distribute extremes among all groups; Testing – where multiple tests change subjects’ response – use experiment types that are random assignment friendly that do not use pre-tests.
