The correlation between two equivalent forms of an objective test administered in immediate succession enables one to determine the proportion of error variance due to
A) item homogeneity.
B) temporal fluctuation.
C) item sampling.
D) scorer reliability.
E) a and b

Question

Quizplus · Accepted Answer

The correlation between two equivalent forms of an objective test administered in immediate succession primarily helps in determining the proportion of error variance due to item sampling. This is because the equivalent forms are designed to measure the same constructs, thus any variance is likely due to the differences in the specific items included in each form.
