Item Analysis provides statistics on overall test performance and on individual test questions. This These data helps help faculty recognize questions that might not adequately discriminate between students who understand the material and those who do not. Faculty can use this information to improve questions for future tests or to adjust credit on current attempts. Ineffective or misleading questions are identified easily, corrected in the Test Canvas, and are re-graded automatically.

• In Progress Attempts - the number of students currently taking the test that have not yet submitted it

A discrimination value is listed as Cannot Calculate when the question's difficulty score is 100% or when all students receive the same score on a question. Questions with discrimination values in the Good and Fair categories are better at differentiating between students with higher and lower levels of knowledge. Questions in the Poor category (less than 0.1) are recommended for review.
• Difficulty - this area shows the number of questions that fall into the Easy (greater than 80%), Medium (between 30% and 80%) and Hard (less than 30%) categories.
