Question

Quizplus · Accepted Answer

The pattern of mean scores across ages does not show a clear linear relationship, but rather a curvilinear one. There seems to be an increase in conservatism from age 18 to 30, a plateau from age 30 to 45, and a decline from age 45 to 60. Therefore, the correlation between age and political conservatism is best described as curvilinear.
