It is frequently presumed that as individuals get older, they become more politically conservative. A political science student wants to verify this postulate. Using secondary data, the student ran a chi-square analysis of the age-group (18–35, 36–55, 56–80) and self-described political affiliation (liberal, moderate, or conservative). The results of his analysis are provided in the tables below, but the student is having difficultly explaining the results. Address the following:
Describe the overall findings of the chi-square in the output, including the cell contributions, based on the standardized residuals.
What conclusions can the student make concerning this postulate?
