Multiple Choice

Use the following information for following questions:. Often college students taking an
introductory course in psychology are required to participate in research experiments. One experiment
was performed to see if using colored paper increased reading comprehension. One hundred students
enrolled in an introductory college psychology course volunteered to participate in the study. Fifty of the
students were randomly chosen to read a chapter in a psychology test that was printed on yellow paper
and the remaining fifty students were given the same chapter to read printed on white paper. After
reading the chapter, each student was asked to answer a series of questions to test his/her comprehension.
The results indicated that those students reading the chapter printed on yellow paper tended to have higher
comprehension scores than those students reading the chapter printed on white paper.

• A)This was an observational study so the results can be generalized to a larger population.
• B)The participants were randomly assigned to a paper color, so the results can be generalized to a larger population.
• C)The participants were randomly selected, so the results can be generalized to a large population.
