D) .70.
E) It doesn't matter.

Question

Quizplus · Accepted Answer

The coefficient of reproducibility measures the extent to which the same results can be obtained by repeating a measurement or observation. For Guttman scales, a coefficient of reproducibility of at least .90 is considered acceptable. This indicates that the items in the scale have a high degree of internal consistency and can reliably measure the same underlying construct. Therefore, choice B is the best option as it matches the acceptable coefficient of reproducibility for Guttman scales.
