ou want to examine the effects of a speed reading class on reading proficiency. You have an experimental group that attends the class and a control group of participants who do not attend the class. Because you are worried about initial reading ability affecting your reading proficiency dependent measure, you do not split your participants into two groups randomly. Instead, you determine their initial verbal skills based on previously computed standardized test scores. From there, you create pairs of participants with equal verbal skills and assign one participant from each pair to be in the experimental group and the other participant from each pair to be in the control group.

What type of test would you perform to see whether the speed-reading class had a significant effect on reading proficiency?
