Analyzing quiz and exam performance

How to read the Analyze tab for an online quiz or paper exam, find questions to check or reteach, and download the figures as a CSV or PDF.


To see how your class did on a quiz or exam, open it from Assessments in the Control Center and select its Analyze tab. An online quiz shows its figures once at least 3 students have completed it. A paper exam with a class list shows them once at least 5 students have a scored answer sheet, and it points out which questions to check and which to reteach.

  1. Open the Analyze tab

  2. Online quizzes: scores and questions

  3. Paper exams: class figures and charts

  4. Paper exams: questions to check or reteach

  5. Download the figures

1. Open the Analyze tab

  1. Select Assessments in the course sidebar.

  2. Select the quiz or exam you want to look at. You can also open the three-dot menu on its row and choose Analyze.

  3. Select the Analyze tab.


2. Online quizzes: scores and questions

The figures at the top give you the class at a glance:

  • High Score and Low Score: the highest and lowest percentage scores.

  • Mean Score: the average percentage, including overdue penalties and grade overrides.

  • Median Score: the middle score.

  • Mean Elapsed Time: the average time taken, using the one attempt that counts for each student.

  • Standard Deviation: how spread out the scores are, in percentage points.

The chart below counts students in 10-point bands (0 to 9%, 10 to 19% and so on). A score of 100% falls in the top band.

If a student on free access submits graded work, their grade is held until they redeem an access code or buy access. Held grades are left out of every figure, and the note Averages leave out held grades appears under Data last updated.

Each question

Every question appears as a card showing its Item Difficulty (the share who got it right, from 0 to 1), Mean and Median Earned Points, and its Discrimination Index (how strongly getting it right goes with a high overall score). Expand a card to see how many students chose each option, with the correct options highlighted. Multiple answer questions also list the most common combinations chosen.

Where many students chose the same wrong answer, check the wording or the key, then use the Remediate tab to adjust grades or exclude the question. Questions you removed from the quiz are labeled Removed from Quiz and keep their history.


3. Paper exams: class figures and charts

A paper exam with a class list opens on its figures. The first row gives the Mean, Median, High and Low percentage scores and the SD. The second row gives the exam's Reliability (KR-20) (labeled Cronbach's α when questions are worth different points or aren't right-or-wrong), the SEM, and how many students have a scored answer sheet. Hover over any label for what it means. Reliability and SEM need at least 20 students and 5 questions. How these are calculated opens a panel with every rule and formula the page uses.

Choose a view above the score chart:

  • Score distribution: students in each 10-point band, with how many scored below 50%.

  • Each score: one dot per student, the mean and median, and the shape of the scores described in words. Tick Normal reference curve to compare it with a normal curve.

  • Compare: each student's score against one other measure, such as their course average before this exam, another graded quiz or exam, videos watched, chapters completed or their section. The page says how strong the link is and when it could be chance.


4. Paper exams: questions to check or reteach

Under the chart, Questions to look at sorts questions into three lists:

  • To check: stronger students did no better, so the key or the wording may be wrong.

  • To reteach: under half got it right, and stronger students did better.

  • Went well.

When there are questions to reteach, Ask Blended AI to make reteach materials under Questions to look at opens Blended AI with a request already written. You can edit it or send it, and nothing reaches students until you approve it.

Below that, the question table lists every question with its % correct, Top wrong answer and Discrimination (item–rest r). A filled ● marks a question to check and a hollow ○ marks one to reteach. The table opens sorted by Needs attention; use Sort to change the order.

Select a row to open the question in a panel on the right, with each answer, how many students chose it, and its figures. A question to check offers Fix the answer key and Give credit, which open the Remediate tab.

With 5 to 19 scored students, the tab shows no discrimination, reliability or flags. From 20 students everything shows.


5. Download the figures

For an online quiz, use Download PDF at the top right of the Analyze tab. It appears once at least 3 students have completed the quiz.

  1. Select Download PDF.

  2. Leave Include questions and answers on to show each question's wording and choices, or turn it off to show each question only by its number, type and points.

  3. Select Download.

For a paper exam, Item statistics (CSV) and Report (PDF) sit beside How these are calculated. The CSV has the whole-exam figures and one row per answer to each question, so you can check them in R, SPSS or Excel.

Both reports hold class totals only, never student names, emails or individual scores. When fewer than 10 students are counted, the download window warns that the totals could identify individual students, and the report leaves out the High and Low scores.

To look at one student's submission, adjust a score or add an attempt, see How to Manage Student Assessment Grades.
