2. Research on heterosexism (the degree to which people think heterosexuals are better than
or deserve more civil rights than non-heterosexuals) indicates that older
people tend to be more heterosexist. Test this hypothesis.
Age is measured in years and
ranges from 18-93.
Heterosexism is a scale that
ranges from 6-17, which was composed from adding Likert responses to 5
attitudinal questions. The higher the
score on the scale, the more heterosexist people are.
r=.25, p = .000 (one tailed)
