Description

The article scales each sentence's difficulty by the same method used for vocabulary words: given the per cent of pupils translating it correctly, its position is located on the base line of the normal frequency surface in P.E. deviations. Two assumptions are made: "that ability to translate Latin is distributed normally, and that the real variability for each year is approximately the same." A reference zero point of -3.8 P.E. obviates plus and minus values, and general scale values combine year values using the intervals between year medians.

Accounts

  • P.E.-based scaling of sentence difficulty assuming normal distribution and equal year variability: The article scales each sentence's difficulty by the same method used for vocabulary words: given the per cent of pupils translating it correctly, its position is located on the base line of the normal frequency surface in P.E. deviations. Two assumptions are made: "that ability to translate Latin is distributed normally, and that the real variability for each year is approximately the same." A reference zero point of -3.8 P.E. obviates plus and minus values, and general scale values combine year values using the intervals between year medians. (Henmon (1917))
