24. Gibbons and colleagues (2006) surveyed 152 college students in Guatemala on their beliefs about machismo (a strong sense of masculinity), their attitudes toward women, and their beliefs about adoption. As shown in Table 11, the researchers used three t tests for independent means to examine whether female and male students differed on these beliefs and attitudes. The scales were scored so that higher scores were for more positive attitudes about machismo, more egalitarian (equal) gender beliefs (which were measured using the Attitudes Towards Women Scale for Adolescents, abbreviated as AWSA in Table 11), and more favorable beliefs about adoption. Explain the study results to a person who has never had a course in statistics. ADVANCED TOPIC:
