Question analysis provides statistics on overall performance, assessment quality, and individual questions. This data helps you recognize questions that might be poor discriminators of student performance that needs review. Reports expire after 14 days.
The Question Analysis page displays tests you could run the report for. If students have not yet completed a test there will not be enough data to run the report.
For example:
Access to the question analysis report
You can access this report from:
An assessment's menu on the Course Content page.
Course Analytics page > Question Analysis tab
Gradebook, list or grid view
The assessment summary provides an overview of:
- how well the questions differentiate between students who know the work, and those who do not,
- the difficulty the assessment.
- Each question's analysis to indicate if review is needed.
Click on the title of a question to access its detailed analysis. The question text and answer choices appear. You can see the percentage of students who answered each choice correctly.
Use Question analysis to improve questions for future assessments; or to correct misleading or ambiguous questions in a current assessment.
E.g.
In a Multiple Choice question, an equal number of students chose A, B, and C. Examine the answer choices to determine if they're ambiguous, if the question is too difficult, or if the material wasn't covered.
A question is recommended for review because it falls into the hard difficulty category. You determine the question is hard, but you keep it to adequately evaluate your course objectives.
A Multiple Choice question is flagged for your review. More Top 25% students chose answer B, but A is the correct answer. You realize you didn't choose the correct answer when you created the question. You edit the assessment question and it's automatically regraded.
