Viewing quiz statistics

You can view and export quiz statistics to a CSV file for data analysis. The CSV file contains all applicable information on the quiz so that you can query, sort, and evaluate the data without being connected to the learning management system. In this view, you can see a list of quizzes for the course. The average grade for each quiz displays beside the quiz name.

Notes
  • All statistics are calculated based on a user's first attempt of the quiz. If a question is changed after attempts have occurred, then only the attempts on the newest version of the question are included in the statistical calculations.
  • Average grade is calculated only for first attempts of the quiz.

  1. On the Manage Quizzes page, click Statistics from the context menu of the quiz you want to view.
  2. On the View Statistics page, click the User Stats, Question Stats, and Question Details tabs to view statistics broken down by user and by question.
  3. Click Export to CSV file if you want to save the quiz's statistics to your computer.

NoteThe system will export the statistics only from the tab you are currently viewing.

Understanding User Stats

User Stats CSV files contain performance data by user, including the user’s Org Defined ID, username, first name, last name, quiz score, the value the quiz was graded out of, the user’s score as a percentage, the class average, and the standard deviation for the class.

TipCreate a column in the CSV file to calculate the median score on the quiz to consider the class’s performance from a different perspective. Use the formula <=median(x1:x5)> to calculate the median.

Understanding Question Stats

Question Stats CSV files contain data about the average score on questions by points and percentage, as well as the standard deviation, discrimination index, and point biserial for each question.

The question title, text, bonus status, and difficulty level are included in the CSV file so that data can be analyzed without referring back to the learning management system.

TipYou can sort, query, hide, and delete data in the CSV file to help your analysis and create charts or graphs to visually represent trends.

Understanding Question Details

Question Details CSV files contain detailed information about each question in the quiz, including a list of all of the answers provided for each quiz attempt, how many users chose each possible answer, the total number of responses, and the average score, standard deviation, point biserial, and discrimination index for each question. Question Details reports can help you evaluate trends in answers and look for questions that were unclear or difficult for a number of users.

The question title, text, bonus status, and difficulty level are included in the CSV file so that data can be analyzed without referring back to the learning management system.

TipCreate a column that calculates the average score for all question attempts as a percentage by dividing the Average Score column by the Out Of column and multiplying by 100. Next, create a custom filter for the new Attempt Average column that displays only rows where the attempt average is less than 51%. This way you can quickly review questions that users struggle with and adjust grades or your lesson plans accordingly.

Understanding statistic types

NoteThe discrimination index and point biserial are rendered more inaccurate the more edits you make to a quiz.

Statistic type What is measured

Standard deviation

The standard deviation indicates how much scores vary from the average, ranging from 0% to 100%. A high standard deviation indicates that scores are spread out from the average, whereas a low standard deviation indicates that scores are close to the average.

Discrimination index

The discrimination index indicates how well a question differentiates between high and low performers. It can range from -100% to 100%, with high values indicating a "good" question, and low values indicating a "bad" question.

Point biserial

The point biserial correlation coefficient is an analysis applied to multiple choice and true/false question types that have only one answer with a weight of 100%, and all other answers with a weight of 0%.

The point biserial correlation coefficient relates individuals' quiz scores to whether or not they answered a question correctly. It ranges from -1.00 to 1.00, with high values indicating a "good" question, and low values indicating a "bad" question.

Note Only first attempts with scores between 0% and 100% on a question are included in that question's statistics.
