A one-group pretest-posttest design is an example of which of the following?
A) A crossover design
B) A true experimental design
C) A quasi-experimental design
D) A retrospective design
C
Feedback:
Quasi-experiments involve an intervention but lack randomization and sometimes even a comparison group. Strong quasi-experimental designs introduce controls to compensate for these missing components. In crossover designs, people are exposed to more than one experimental condition in random order and serve as their own controls. Experiments involve an intervention; control; and randomization or random assignment. Retrospective designs involve collecting data about an outcome in the present and then looking back in time for possible causes.
