Quizplus · Accepted Answer

The correlation between test items and total test scores (option B) and the correlation between subtest scores and total scores (option C) both provide evidence of homogeneity in a test. Option A (correlation between a test and some criterion) is not directly related to homogeneity, but rather to validity. Therefore, the best choice is D (both b and c).
