LABORATORY OF PSYCHOLOGY OF COLUMBIA UNIVERSITY PHYSICAL AND MENTAL TESTS
On the back of this sheet will be found the record of the student to whom it is sent, together with the results obtained with about 250 college freshmen. The individual student may thus see how certain of his physical and mental traits compare with those of other students. Some of the records are given in percentages: Thus, in the case of eyesight, if the student has a record of 44 cm. or under he is among the third or fourth having the worst eyesight and should consult an oculist. Others of the records are given in averages, and the student can readily see whether he is above or below the average. After the average is given a number in parenthesis which is the probable error. If the record of an individual departs from the average by less than this quantity he belongs to the half of the students who are medium or normal. Thus in the case of the reaction-time, if a student has a time more than 0.019 sec. below 0.159 sec. he is among the quarter of the students who are the quickest.
