Homogeneity refers to the extent to which items on a test measure the same construct or trait. Measures specific for testing homogeneity include B) Item-to-total correlation, which assesses how well each item correlates with the total score; D) Split-half reliability, which involves dividing the test into two halves and correlating the scores; E) Kuder-Richardson coefficient, specifically KR-20, which is used for dichotomous items; and F) Cronbach's alpha, which is used for tests with items on a continuous scale and assesses internal consistency.
