Using the study variables from above and their levels of measurement, which type of statistical analysis would be conducted for the following pairs: Religious affiliation and meal preference, Money earned last year and risk of heart failure, Time of day (12 hr) and levels of radon (Likert Scale)?
Understand the Problem
The question is asking which types of statistical analyses would be appropriate for given study variables and their respective levels of measurement. It lists three different pairs of variables and suggests corresponding statistical methods for analyzing them.
Answer
Chi-square test, Logistic regression, Spearman's rank correlation.
For Religious affiliation and meal preference, use Chi-square test. For Money earned last year and risk of heart failure, use Logistic regression. For Time of day and levels of radon (Likert Scale), consider Spearman's rank correlation.
Answer for screen readers
For Religious affiliation and meal preference, use Chi-square test. For Money earned last year and risk of heart failure, use Logistic regression. For Time of day and levels of radon (Likert Scale), consider Spearman's rank correlation.
More Information
Statistical analysis methods depend on the types of variables involved and their levels of measurement. Different statistical methods are suited to different combinations of variable types.
Tips
Avoid using parametric tests on non-normally distributed data like Likert scales unless assumptions are met.
