Sadhna is calculating the difficulty level of the test questions. In one of her questions she notices the difficulty level has a value of 90. What should Sadhna do to the item ?

Correct option is B

A difficulty level of 90 means that 90% of students answered the question correctly, indicating that the question is very easy. In most cases, questions with a high difficulty index (above 80 or 85) are considered too easy and may not effectively differentiate between high-performing and low-performing students. Therefore, the item should be discarded from the test, as it does not challenge students sufficiently or provide meaningful data about their abilities.

Information Booster:

1. The difficulty level, or p-value, of a test item measures the proportion of students who answer it correctly. The higher the value, the easier the question.
2. A question with a difficulty level of 50-60% is considered moderately difficult, providing a better balance for assessment.
3. Test items that are too easy do not effectively measure students' true understanding or critical thinking abilities.
4. Items with a difficulty index above 85% often fail to discriminate between different levels of student performance.
5. Test construction aims for a variety of difficulty levels, ensuring the test assesses a range of abilities.

Additional Knowledge:

• (a) The item should be kept in the test: Since the question is too easy, it should not be kept, as it does not offer much discriminatory value.
• (c) The item is moderately difficult for the test: A difficulty level of 90 means the question is very easy, not moderately difficult. Moderate difficulty typically falls around 50-60%.
• (d) The item is a good question for the test: A difficulty level of 90 makes the question less effective for assessing student performance and learning outcomes, so it should not be considered a good question.
