This paper illustrates two advantages of using canonical correlation as a tool in the discriminant problem, with more than two populations, rather than the more familiar Anderson discriminant function. These advantages are: i) simultaneous test of significance as to whether the means of the populations differ and ii) given that the means differ, a graphic tool to illustrate the nature of the difference between the populations. If there are natural groupings of the populations, an analytic technique is also available to augment i). This latter property is also demonstrated in the accompanying application.
