Binning them into a histogram and comparing with a Gaussian is one way, but all the departures from the Gaussian lie out on the tails, where they can be hard to see. Also enclosed is a sample script containing 2 examples. Outliers appear as deviations from the linear locus. As part of my research work I have a need for non-parametric statistics. This would be trivial except that tied observations must be assigned the average of the ranking that would have been assigned to each individually.
