Within the Discussion Board area, write 400-600 words that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.
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?
