Dr Cardenas studied political attitudes among di erent group

Dr. Cardenas studied political attitudes among di erent groups of 20-, 40-, and 60- year- olds. Political attitudes were found to be most conservative in the age-60 group and least conservative in the age-20 group. What type of method was used in this study? Can you conclude that people become more politically conservative as they get older? Why or why not? Propose alternative ways of studying this topic.

Solution

This is an observational study. If it is an experimental design, we need to perform Chi-square test, odds ratio, or one way ANOVA. Or simply, if the data is available for each age group, the coefficient of variation is used to determine which age group is conservative.
