Dr. Pow is interested in whether exposure to TV advertisements has a different impact on girls' self-image than it does on boys' self-image. To examine this question, she conducts a quasi-experiment. Why doesn't Dr. Pow conduct a true experiment instead?
a. She cannot conduct a true experiment, because people cannot be randomly assigned to be girls or boys.
b. She cannot conduct a true experiment, because self-image is not directly observable.
c. She could conduct a true experiment if she wanted to, but she probably has a very small sample size, so in this case a quasi-experiment is better.
d. She could conduct a true experiment if she wanted to, but she is probably interested in real-life TV exposure (and probably doesn't want to manipulate this variable).
