This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1916 edition. Excerpt: ... children in the second grade made a score of o in Scale A, which means that they received no score at all. Between these children and the median of the second grade, however, there were 404 children, which is 30.65 per cent of all in the second grade. Reference to Table XIII shows that a difference of 30.65 per cent from the median of a normal distribution means a distance of 1.283 P.E. If this were our only evidence, therefore, we might locate our arbitrary zero-point at 1.283 P.E. below the median of the second grade. Table I also shows that 19 of the 1437 pupils in the third grade made a score of zero, while 48.68 per cent scored above zero but below the median of their grade. This would locate the zeropoint in Scale A at 3.291 P.E. below the third grade median. We have already determined (Table XXVII) that the third grade median is 1.599 P.E. above the second grade median. The zero-point in Scale A is therefore located by the third grade distribution at 1.692 (3.291-1.599 = 1.692) P.E. below the second grade median. The median score of the second grade on Language Scale A is shown by Table I to be 4.5912, and the quartile 2.0848. Assuming that the quartile is equal to the P.E., as it is in a perfectly normal surface of frequency, we find by dividing the score by the quartile that the second grade median is 2.2022 P.E. above zero. The median score of the third grade is shown by Table I to be 8.9864. Table XXI shows the average of the quartiles of grades II and III to be 2.7487. Dividing the score by this average of the quartiles places the third grade median at 3.2693 P.E. above zero. From this determination, then, zero would be 1.670 (3.269-1.599 = 1.670) P.E. below the second grade median. This makes the fourth determination of the...
