Difficulty index is based on calculation of two indices, that is, the discrimination index and the difficulty index.Question 6Answera.trueb.false

The question seems to examine the relationship between the difficulty index and other indices used in educational assessment.

In assessment theory, the difficulty index indeed measures how challenging a test item is for the test takers, while the discrimination index evaluates how well an item differentiates between high-performing and low-performing students.

1. Discrimination Index: This index indicates the extent to which a question effectively differentiates between students who understand the material and those who do not. A high discrimination index suggests that the question is easier for those with higher knowledge.

2. Difficulty Index: This index reflects the proportion of students answering the question correctly. A low difficulty index means the item is challenging for most.

Since both indices contribute to understanding a question's overall effectiveness, the statement provided in the question is true.

Thus, the answer is:
