What statistical test should I use if I have three independent groups of interval data and would want to check whether their means are significantly different? I'd also note that the samples sizes of each group is different (N1= 50, N2= 10, N3=13).
Would it be wiser to compare one with another and then do the same for the other two other pairs? (G1=G2; G2=G3; G1=G3)?
I understand that one-way ANOVA and a Tukey's post-hoc would be the best option but does the difference in sample size pose a problem?
