Suppose you wanted to test the effects of a college writing program on success in other classes. The experimental group consisted of freshmen who had enrolled in the writing class; the control group consisted of freshmen who had not enrolled in the writing class. Subsequent performance of both groups in a writing-intensive history class was measured. A potential confound in this study is:
a. maturation.
b. testing.
c. selection.
d. mortality.
Question 2
If in the course of an experiment you repeat measurements of the same individual, you introduce a confound called:
a. maturation.
b. history.
c. selection.
d. testing.
