In several of the tests, especially sensation-areas, force of movement, perception of pitch, of size and of time, and memory for size, the number of trials is not sufficient to establish certainly the place of the student among the others.
Tests such as these are of importance for science. They teach us the normal type of individual and the normal variation from this type. They show us how different classes in the community differ, and on what conditions of heredity, education, etc., these differences depend. They show us how physical and mental traits are interrelated, how they alter with growth, and on what conditions development depends. The tests should be of interest to the individual as they show how he compares with his fellows, indicating defects and special aptitudes, and if repeated later in the college course or in after life the comparison may prove of great value. This record should be compared with the measurements taken in the gymnasium.
