Although both designs identify an independent variable, the nature of the groups (randomized versus nonrandomized) means that manipulation may result in different results. c.

Although both designs identify an independent variable, experimental designs identify it before the research is initiated, whereas quasi-experimental designs identify it after the data are analyzed.
