H 0^ is the differencein difficulty between only and even ; K O^, between even and smoke ; P O^, between smoke and chicken ;S O*, between chicken and front; and T 0^, between front and another. When less than 50% of the judgesregard the first of a pair of words as easier, the second is, of Arrangement of Words of List by Teachers Judgments 73 Y. Fig. 22.

Such is the case in the only-even and chicken-frontpairs. The scaling of these six words is diagrammatically shownin Fig. 22 by producing each median vertical to meet the line will be seen that the order of difficulty is not the same asthe order obtained by testing. Table XXIX shows for the entire 50 words the per cent ofteachers who judged each word easier than the following wordand the rank of each word for difficulty by record and byteachers judgments. In spite of the fact that the opinion ofsingle teachers is so unreliable, the combined judgments of agroup as large as 200 yield an arrangement which agrees closelyenough with the arrangement by record to confirm and supportthe latter in no small degree.
