Description	Watson's U-squared statistic calculates Watson's non-parametric two sample U-squared statistic for circular-normal data which provides a criteria to test whether 2 samples differ significantly from each other. The difference is not specified; it may be in the mean, the angular variance, or something else. Data should be two independent random samples of circular observations drawn from populations with a continuous distribution. Data should not be grouped, or if it must be grouped, class intervals should be no larger than 5 degrees. For large samples of grouped data (where there are likely to be many ties), the test may not be applicable.
