unbalanced sample sizes

Jon Oh
Hi,
I want to compare several groups using one-way ANOVA, but the group sizes are unbalanced. For example, I have one group consisting of 200 people, another with 90, and the third with 22. I know these unequal sizes are problematic especially when homegeniety is violated. Is there a solution to make sure the test result will be reliable? Thank you
