Most elisions of the test were judged of average difficulty (83.2%), with 9.3% more-than-average and 7.5% very difficult, yielding frequency-based weights of .048, .427, and .533.¶

Subclaims¶

q2 i? Pooling subjects' introspective difficulty ratings, 83.2% of elisions were of average difficulty, 9.3% of more than average difficulty, and 7.5% very difficult. → Walter R. Miles and Julian E. Butterworth 1912 q2 i? On the basis of these frequencies the authors derived relative values of .048, .427, and .533 for average, more-than-average, and greatest-difficulty elisions. → Walter R. Miles and Julian E. Butterworth 1912

Combined introspective ratings from the 25 subjects produced these pooled frequencies; the authors then reasoned that "the very difficult elisions are 11.1 times as difficult as words of average difficulty" and reduced the proportions to fractions of unity (.048, .427, .533).

"83.2% of the elisions were marked as of average difficulty. 9.3% of the elisions were marked as of more than average difficulty. 7.5% of the elisions were marked as very difficult."

• Applying the difficulty weights yields highly unequal per-elision values within a sentence, e.g. elision 8 of unit 1 worth 15.19% of the unit versus 3.99% for several others. — related
• Perceived task difficulty ratings show a strong relation to Rasch-estimated relative task difficulty, supporting construct validity of the single-item scale — related
