Extracted text: 7 7 4 4 3 2 2 1 1 1 2 3 4 1 2 3 4 LONG QUESTIONNAIRE SCORE SHORT QUESTIONNAIRE SCORE Complete the following sentences by trusting your eyes to see meaningful differences in the two graphs. The range for Graph I is the range for Graph II. The mean for Graph I is the mean for Graph II. The variance for Graph I is the variance for Graph II. This implies that the shorter questionnaire will be than the longer questionnaire at detecting differences before and after the intervention.


Extracted text: A researcher designs an intervention to combat anti-Arab oppression. She also designs a questionnaire to measure anti-Arab oppression so she can test the participants' level of anti-Arab oppression 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 0 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 long version, and Graph II graphs the results from the short version.
