I have a data table detailing various histological parameters among 3 groups of patients- DLE, SCLE and ACLE.
I would like to know how we could do an analysis on the strenghth of the association of a parameter with a particular group.

If the parameters are continuous variables, you can do an analysis of variance for each one. That will isolate any group differences in the means. You can also measure effect size, d, as the difference between two groups' means divided by their pooled standard deviation. If the parameters are categorical (including binary), you can do a Chi-Square test to see whether there is any disproportionality. Depending on the way this test is structured, you could compute an effect size using a metric such as Cramer's V, lambda, or the contingency coefficient. |
