of the distribution was divided by the square root of the number composing it (here 2) in order to find the measure of reliability of the average. This measure of reliability, being in terms of an A. D., was multiplied by six-sevenths to turn it into a P. E. While each P. E. is thus itself subject to consider- able unreliability, having been obtained from only two measures, the average of all the P. E.'s is a very reliable measure of the limits above and below the value within which each value ...as given would have an equal chance of falling were it to be obtained from an infinite number of judgments. This average for fourteen samplers is .159. 14. The amalgamated measure of value for the twenty-two samplers given in column 6 of Table VI served as the basis for the final selection of samplers which should constitute the completed scale. Fifteen of the twenty-two samplers were chosen for this purpose. They were so selected that the values between each suc- cessive pair should be as nearly as possible equal.
