In this paper, a seemingly contradictory experimental result concerning Fisher criterion is first exhibited. Then, we analyze this result from the statistical correlation point of view and give a reasonable explanation. More importantly, we emphasize that Fisher criterion is not an absolute criterion, and, it should be associated with the statistical correlation together to assess the descrimination of a set of discriminant vectors.
