The reader who is mathematically inclined may wish to find the median point in the distribution, the point which bisects the distribution. To find this, one needs to study his facts carefully and make such assumptions as seem most probable for the facts which are not perfectly apparent. For example, of the three persons who scored 2 points, one individual may have had the third problem thought out and have been in the very act of writing the correct answer to it when the time was up, while another may have just finished problem two without having begun to read the third problem, and the third person may have been right in the middle of his thought about problem three. Not knowing what the exact truth is, we may assume that of the three who had a score of 2, one’s true score was between 2 and 2.33, another’s was between 2.33 and 2.66 and that the third’s was between 2.67 and 3.00. If we count out the five who scored 3 or higher, we shall still require half of the distance represented by the next highest individual in order to have counted out 5.5 (half of 11). If our assumption is true, then, we shall need to count half way down from 3.00 to 2.67 in order to find the median point, 2.83. The calculation of the median point is not necessary, however, unless there is a very large number of cases in the distribution and unless very accurate comparisons must be made. In passing it may be said that the calculation of the median point at 2.83 is just as sensible and just as accurate as the calculation of the average point at 3.18, and that the median point is a much more useful measure of the distribution than the more commonly used average. The user of the Mentimeter tests will not, under ordinary circumstances, be satisfied with interpreting an individual’s score merely by indicating its direction from the median, mode or average of a group. It will not usually be sufficient to say “He made the modal or most popular score,” or “His score was lower than the average,” or even “His score was higher than the median.” Some indication will be desired as to how much better or poorer a given score is than the median, or just what percentage of the standard group made better scores. An illustration of the method to be employed in such calculations and a review of the method of finding the median is given below in connection with a distribution of scores on one of the Mentimeter tests.
