A. Item is too easy
B. Item is difficult
C. Item is acceptable
D. Item is easy
Answer is = B
You are absolutely right! In the context of item analysis, a facility value of less than 0.20 indicates that the B. Item is difficult.
Here’s why:
- Facility value: This is a statistical measure used in educational assessments to analyze the difficulty of test questions (items). It represents the proportion of examinees who answered the question correctly.
- Interpretation of facility value:
- A facility value closer to 1 (e.g., 0.80 or higher) suggests a higher proportion of students answered correctly, indicating an easy item.
- A facility value closer to 0 (e.g., 0.20 or lower) suggests a lower proportion of students answered correctly, indicating a difficult item.
- A facility value around 0.50 suggests roughly half the students answered correctly, which is considered an item of acceptable difficulty.
Therefore, a facility value of less than 0.20 signifies that a relatively low percentage of students answered the question correctly, making it a difficult item
