I have another question. Homogeneity of variances was violated. How do I continue?

I have another question. Group sizes are unequal in my sample because of some practical reasons. What would be the risk if the assumption of homogeneity of variances is violated in this case?

If group sizes are vastly unequal and homogeneity of variance is violated, then the F statistic might be biased when large sample variances are associated with small group sizes. When this occurs, the significance level will be underestimated, which can cause the null hypothesis to be falsely rejected.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
