Lesson (37% correct) willbe at a point above zero between which and zero are 13% ofthe cases of a normal frequency surface. Table XIV locatesthis point at +.49 (Point 2, Fig. 13). Only (65% Scaling the Words 43 correct) is at —.

Words rated above 50%are located below the median: those under 50% are above themedian. Their distances from the median are negative in thefirst case and positive in the second. Assuming the same form of distribution for the 4th gradewe find that even (79%) is located at — , only (75%) at precisely — ,, and pear (42%) at +.30 ,Similarly for each grade by using the per cents of Table III andIV and the equivalents of Table XIV we may place all. r^^£; P£. i / \- -fzi^t.

Table XVII gives the per cents and P,E. equivalentsof the 50 words of the Preferred Lists which from now on willbe treated as one list. Figs, 14, 15, 16, 17, 18 and 19 show howthe words appear when arranged on a linear scale for eachgrade. For the meanings of the numbers, each of which refersto a word of the Preferred List, see Table XVII or Appendix II,Table XVII with its corresponding figures (14 to 19) aflFordsstandards for grade performances. As will be observed, the P,E,values of all the words are calculated for each grade with refer-ence to the median of that grade, which is called zero. Theiruse may be illustrated with reference to the 4th grade. We maytest a pupil of that grade by beginning with the easiest word andproceeding to the next hardest and the next and so on.
