  • How should I test significance between 2 groups?

    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%.

    What significance tests you use will depend on multiple factors like how the dependent and independent variables are measures and distributed, how the groups are sampled from the population, and whether the groups are independent or not. These readings should inform your decisions: https://www.biochemia-medica.com/en/...04/fullArticle and https://stats.idre.ucla.edu/stata/wh...s-using-stata/

      Notwithstanding the useful advice by Tom, -ttest- is pretty much always appropriate. There might be other tests which are more appropriate, but still -tttest- is appropriate in any context I can think of.
