Once I publish my Quiz, what kinds of quiz statistics are available?

You can view quiz statistics for quizzes that have been published and have at least one submission.

Note: Quiz Statistics will not be available until at least one student has completed the quiz.

View Statistics

Instructors can view an entire quiz summary that shows all score percentages. The quiz summary also shows the quiz average score, high score, low score, standard deviation (how far the values are spread across the entire score range), and average time of quiz completion [1].

The quiz summary chart is interactive; users can focus on a specific segment of the chart by selecting a range with their cursor, such as viewing the number of students who scored between 0 and 50 percent [2].

If a student had multiple assignment attempts, you can view past attempts in SpeedGrader. Quiz stats will only display the kept score for the student (highest score or latest score).

View Analysis Reports

When instructors generate an analysis report, Canvas shows the last time the report was generated. If there is an error with the report, instructors can retry the option or cancel the analysis completely.

Download csv files to view Student Analysis or Item Analysis for each quiz question to counts all student attempts in the statistics. For more detailed information on how item analysis is calculated, please refer to the Item Analysis PDF.

Limitations within Item Analysis

Item analysis may not generate results within specific quizzes. Here are a few limitations to consider within analysis reports.  

  • Quiz analysis only applies to True/False and Multiple Choice Questions.
  • If a student does not answer a quiz question and drops the number of responses below 15, the quiz question will not appear on the item analysis. For instance, if 16 students take a quiz, but two of them skip question #4, question #4 will not appear on the item analysis.
  • The initial iteration of item analysis is designed to work with quizzes that deliver the same questions to all students. Therefore, if you generate the item analysis csv for quizzes that pull from a question group, the csv will generate a line representing each version of the quiz.

View Question Breakdown

You can view a breakdown of each question in the quiz. Toggle the expand button to expand or collapse all details for all quiz questions.

View Expanded Question Breakdown

Each question displays answer bars relating to the percentage of each answer choice. You can also hover over the answer bars to see the percentage and number of students in the tooltip [1]. Expanding the question shows the exact percentage of each answer below the answer bars with the exact answer choices from your students [2].

View Discrimination Index

Quiz statistics for True/False and Multiple Choice quiz questions include an item discrimination index, which attempts to look at a spread of scores and reflect differences in student achievement. This metric provides a measure of how well a single question can tell the difference (or discriminate) between students who do well on an exam and those who do not. It divides students into three groups based on their score on the whole quiz and displays those groups by who answered the question correctly.

Lower discrimination scores (in red) are scored +0.24 or lower [1]; good scores (green) are +0.25 or higher [2]. An ideal discrimination index shows students who scored higher on the quiz getting the quiz question right, students who scored lower on the quiz getting the quiz question wrong, and students in the middle range on either side. A discrimination index of zero shows all students getting the quiz question right or wrong.

View Distribution Scaling

Quiz statistics for Fill-in-Multiple Blanks, Multiple Dropdowns (often used for Likert Scale questions), and Matching questions are animated to distinguish between answer choices. When each answer is selected, the bars in the answer distribution chart are scaled according to the answer response.
