Biplots and triplots enable you to look at the relationships among cases, variables, and categories. Therefore, we'll next create a single overview table for our five variables. Is there a best test within SPSS to look for statistical significant differences between the age-groups and illness? SPSS gives only correlation between continuous variables. b)between categorical and continuous variables?
