The difficulty level measures how hard a test question is. It's typically calculated as the percentage of students who answered the question incorrectly.
Follow these steps:
Total students = 50
Students who answered correctly = 10
Number of incorrect answers = Total students - Students who answered correctly
Number of incorrect answers = 50 - 10 = 40
Difficulty Level = (Number of incorrect answers / Total students) $\times$ 100%
Difficulty Level = (40 / 50) $\times$ 100%
Difficulty Level = 0.8 $\times$ 100%
Difficulty Level = 80%
A difficulty level of 80% indicates that the question was challenging for a large majority of the students.
