Abstract: Abstract Except in chapter 1 and in sections 3.6, 3.9, 3.10, and 15.3 to 15.5, the concepts and methods discussed up to now in this book concern the analysis of a single variate at a time. The simultaneous analysis of two variates will be taken up in this chapter. In order to provide as concrete an example as possible, Figure 19.1.1 represents the scatter diagram of skull length X and skull width Yin 76 male (black dots) and 53 female (white dots) North American martens. The measurements were taken with vernier calipers and have an accuracy of 0.1 mm (Jolicoeur, 1963b, 1963c). The fact that black dots are located mostly higher and more to the right than white dots in the scatter diagram appears to indicate that males are larger than females.
