What other independent variables might explain differences in the “perception of police scale” constructed in Exercise 8.2? Select three more independent variables besides sex, and conduct additional t tests with this scale as the dependent variable. Write a sentence or two summarizing the results of these tests.*

Exercise 8.2

Using Demonstration 8.3 as a guide, construct a summary scale for “perception of police” using plp_q130, plp_q150, and plp_q160 in place of pcc_ q120,pcc_q130, and pcc_q140. Test for the significance of the difference using sex as the independent variable. Write a sentence or two summarizing the results of this test.
