How do I view statistics about a completed assessment?
You can view statistical information about student submissions to an assessment, such as average scores and standard deviation.
For information on entering assessment grades and comments, see How do I grade Tests & Quizzes?
Go to Tests & Quizzes.
Select the Tests & Quizzes tool from the Tool Menu of your site.
Select the Published Copies tab.
Select the Published Copies tab to view the assessments that have been released to students in your site.
Go to the assessment submissions.
Select Scores from the Action drop-down menu for the assessment.
Alternatively, you may select the number of student submissions in the Submitted column to view the submissions.
Select the Statistics tab.
View Statistics page.
The Statistics page displays information including the number of students who submitted the assessment, average scores, standard deviation, how many students selected particular responses to each question, and the percentage of students who answered automatically-graded questions correctly.
Below are descriptions of the various elements on this page.
View Options
If the assessment allowed multiple submissions, or a student submitted a retake, two View options may be available on the Statistics page:
- The Highest or Last Submission
- All Submissions
Available view options depend on the assessment's Recorded Score setting; for example, if the highest score was recorded, the Highest Submission displays by default. If the average score was recorded, All Submissions will be the only option available on the Statistics page.
Grade Statistics
The Grade Statistics table includes the following. Example values below are for a quiz where 9 students earned the following scores: 65, 70, 86.67, 88, 90, 93.34, 95, 95, 100.
- Submissions: The total number of student submissions to the assessment, e.g., 9.
- Total Score Possible: The assessment's total point value, e.g., 100.
- Mean: The average of all the scores students earned, e.g., 87.
- Median: The middle score among the set of scores that students earned, e.g., 90.
- Mode: The score that was earned by the most students, e.g., 95. More than one value may display for the Mode if the same number of students earned different scores.
- Range: The lowest and highest scores that students earned, e.g., 65 - 100.
- Quartile 1: When all the students' scores are listed in order from least to greatest, the middle number in the lower half of the scores earned, e.g., 86.67.
- Quartile 3: When all the students' scores are listed in order from least to greatest, the middle number in the upper half of the scores earned, e.g., 95.
- Standard Deviation: A value that indicates how much most students' scores vary from the average (mean) score. For example, with a Standard Deviation of 11.83, students in the class tended to earn an average of approximately 11.83 points more or less than the mean of 87 points.
Final Score Distribution
The Final Score Distribution graph is a bar chart which indicates how many students earned final scores that fall within the ranges of point values indicated.
Ranges of point values are displayed in open and closed intervals. In the graph pictured above:
- Where the Number of Points is [65,69), and the Number of Students indicated on the bar is 1, one student earned a score starting at 65 (closed interval), and less than 69 points (open interval).
- Where the Number of Points is [97,100], and the Number of Students indicated on the bar is 1, one student earned a score starting at 97 through 100 points (closed interval).
Note: Score adjustments entered on the Total Scores screen for students with No Submission will not be included in the Final Score Distribution.
Individual Question Statistics
The information displayed for each question depends on the type of question.
Multiple Choice and True False
For each multiple choice and true false question, the following information is displayed:
- Answer Options: Answers students could select.
- Correctness: Whether the corresponding answer option was correct or not correct.
- Number of Responses: The number of students who selected a particular answer option, along with a progress bar indicating the percentage of students who selected that answer option when responding to the question.
- How many students answered the question, and of those who answered, the percentage who selected all correct answers (and no incorrect answers, for multiple choice, multiple selection).

- Answer Options: Possible correct answers.
- Correctness: In this case, only correct answers are listed.

- How many students answered the question, and of those who answered, the percentage who entered correct answers for all the blanks.
Manually-Graded Questions
For each manually-graded question, such as a short answer/essay, student audio response, or file upload question, the following information is displayed:
- Points Scored: Ranges of possible point values.
- Number of Responses: How many students earned a score that falls within the specified range of points, along with a progress bar indicating the percentage of students who earned scores in that range when responding to the question.
- Responses: How many students submitted the assessment.
- Total Points Possible: The question's point value.
- Mean: The average of all the scores students earned for the question.
- Median: The middle score among the set of scores that students earned for the question.

Matching
For a matching question, the following information is displayed:
- Answer Options: The choices for which students must select matching responses.
- Number of Correct Matches: The number of students who selected the correct match for the corresponding choice, along with a progress bar indicating the percentage of students who selected a correct match for that choice when responding to the question.
- How many students answered the question, and of those who answered, the percentage who made correct matches for all choices.
Calculated Questions
For a calculated question, the following information is displayed:
- Answer Options: As different students may have to answer the same calculated question with different values, the answer options shown are correct and incorrect.
- Correctness: Whether the answer was correct or not correct.
- Number of Responses: The number of students who entered the correct or incorrect answer, along with a progress bar indicating the percentage of students who answered correctly or incorrectly when responding to the question.

Survey Questions
For each survey and survey - matrix of choices question, the following are displayed:
- Answer Options: Possible answers.
- Number of Responses: The number of students who selected that answer, along with a progress bar to indicate the percentage of students who selected that answer option when responding to the question.
- How many students answered that question.
Select the Item Analysis tab.
View Item Analysis page.
If your assessment has automatically-graded questions, the Item Analysis page gives a quick table overview of the percentages of students who answered each automatically-graded question correctly, how many students selected a particular answer option for each question, and how many of the students who submitted the assessment provided No Answer to that question.
Each question is listed as the letter Q with the question number (e.g., Q1, Q2). If the assessment was organized into multiple parts, the part number is included with the letter P (e.g., P1-Q1, P1-Q2, P2-Q1).
Manually-graded questions, such as short answer/essay and student audio response questions, are not displayed at all. Pictured above is an Item Analysis page where Q2-Q10 are shown, because Question 1 is a short answer/essay question.
Note: If the assessment allowed multiple submissions, two view options may be available on the Item Analysis page: either the Highest or Last Submission, or All Submissions. Available view options depend on the assessment's Recorded Score setting; for example, if the highest score was recorded, the Highest Submission displays by default. If the average score was recorded, All Submissions will be the only option available on the Item Analysis page.
