| Summary: | "The object of this volume is to present methods of procedure and data obtained in enough detail to make it unnecessary for others to repeat, except for purposes of verification, the work reported in Volume I. For this reason it has seemed worth while to describe less useful methods and the results obtained with them as well as the methods decided upon and used in the scale in its final form. Because it is believed that our statistical methods of dealing with data are changing more rapidly than our methods of collecting data, raw scores for each of the four groups used in establishing norms have been placed on file in the Library of the University of Minnesota where they can be obtained on request. Sex norms for the group used in establishing chronological age norms for Form I, for the retest group for Form II, and for the group used in determining the mental age norms for Form II have also been placed on file there, as well as the raw scores for the Italian children tested and for the Jewish children. Neither of the two last-named groups is large enough to justify drawing conclusions from the data presented. But if these are combined with data obtained by other workers, the sum total may provide a group of sufficient size for the findings to have significance. Since the number of cases of any one kind to be observed in a given clinic is small, it would seem to be highly desirable for clinical psychologists to make use of every possible method for pooling raw data. Only by so doing can we obtain a large enough group of cases of any one type to yield results that will be statistically reliable"--Foreword.
