I would really appreciate some suggestions concerning an issue.
If I have a dataset with 3 groups, n=6/group originally. Lets say I delete 1 sample from each group because they are outliers. After this move, when I have n=5/group, may I replace this one deleted data with my mean for the 5 samples/group, thus I would have n=6 again? I have a marginal non-significant result p=0.053 and if I do so it reaches significancy. I saw this approach several times used by experimental researchers working with low number of individuals or animals pro group, but I could not tell whether its correct.
Thank you very much for your kind help in advance!
