Discrimination value of more than 0.4 means?

Explanation

A discrimination value of more than 0.4 indicates that the item is considered to be "acceptable" in terms of its ability to differentiate between high-performing and low-performing students.

This means that the item effectively discriminates between individuals who possess the desired skill or knowledge and those who do not.

Such items are valuable for assessing the targeted attribute with clarity and precision, contributing to the overall effectiveness of the assessment process
