Re: Mann Whitney Test

Following is from Pocket Dictionary of Statistics by Hardeo Sahai and Anwer Khurshid (2002), McGraw-Hill, New York:

Mann-Whitney performs a hypothesis test of the equality of two location population parameters (means or medians). It is based on the analysis of two independent samples and calculates the corresponding point estimate and confidence interval. The procedure is used for comparing two independent samples of scores that cannot be compared by means of a two-sample t-test either because the scores are ordinal in nature or the normality or homogeneity of variances assumptions cannot be satisfied. The Mann-Whitney test statistic is equivalent to the Wilcoxon test statistic.

I hope it will be of some help.
