Hi, I haven't been able to find any sources that deal with this issue yet. Any recommendations or thoughts that anyone has would be really appreciated.

My dataset has 6 groups (heterosexual men and women, bisexual men and women, and homosexual men and women), with 20-25 participants per group. The sample is quite diverse--about 60% white and 40% non-white (including black, asian, latino, and mixed-race participants), and the relative proportion of the racial demographics varies across the six groups. Additionally, one of our six groups has a higher mean age than the other groups (38 yrs vs. 29-32 yrs). Is there a recommended approach for accounting for these differences? Many thanks, Victoria
