Excerpt from An Investigation Into the Validity of Norms With Special Reference to Urban and Rural Groups
The applicability of norms, however, depends on many other factors besides the number of cases on which the tests are standardized. One has to consider the composition of the group from the standpoints of variability, sex, racial and national components, etc. Moreover, the original scaling of the test with the possible favoring of one group to the exclu sion of others must be taken into account.
