A researcher designs an intervention to combat anti-Semitism. She also designs a questionnaire to measure anti-Semitism so she can test the participants' level of anti-Semitism before and after the intervention. She tests one version of her questionnaire with 45 statements and a shorter version with 12 statements. In both questionnaires, the participants respond to each statement with a rating on a 5-point Likert scale with O equaling "strongly disagree" and 4 equaling "strongly agree." The overall score for each participant is the mean of his or her ratings for the different statements on the questionnaire. Look at the following graphs. Graph I graphs the results from the short version, and Graph II graphs the results from the long version.
