Hi Frank,
I think most people use a series of Mann-Whitney tests in this situation. If you do this, you will want to set a more conservative level of alpha, using perhaps the Bonferroni correction, to evaluate the results. To obtain the Bonferroni correction, divide the alpha you are using by the number of tests you are doing, and use the result to decide if your results are significant.
Best,
Susan
