Throwing a third hat in the ring, you could set up a permutation test for median, for mean, for 5% trimmed means or any other statistic that suites your substantial question best. I am not arguing in favour of a permutation test, just saying, you have the freedom to decide, which statistic should be tested based on the substance of your research. | |
