I have applied ANOVA on 3 independent groups of unequal sample sizes. I doubt that the ANOVA result are showing Type 1 error because of heteroscedasticity in data points (checked using F-test as well as Bartlett's test). I want to know is there any other good statistical method to solve this problem other than the t-test for unequal variances.

Thanks Suneyna
