I have two groups. I want to measure whether group difference is significant or not. For example, in group 1, the average age is 32. In group 2, the average age is 36. I want to add star in the table if 32 is significant different from 36.
I also have categorical variable cases. For example, in group 1, the black ratio is 57%. The black ratio is 44% in group 2. I want to add * in this row if 57% is significant different from 44%.
