3. More and less variability A researcher designs an intervention to combat homophobia. She also designs a questionnaire to measure homophobia so she can test the participants' level of homophobia 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 1 graphs the results from the long version, and Graph II graphs the results from the short version. Graph I Graph 11 PARTICIPANTS PARTICIPANTS B B 7 7 b b 5 5 I.
