Abstract
This chapter is devoted to a study of contrasts of the class comparison type. With the exception of pairwise comparisons, this is the easiest type of contrast. A class comparison contrasts the average of the population means in one class of populations, with the average for a second class of populations. For example, in §7.1 the contrast of suburban with urbanc = (µ1+ µ2)/2 –µ3was of this type. Here the class of suburban populations had two members whereas the class of urban populations had just one member.
