This dashboard provides visualizations to help users understand the quality of assessments using quiz and question statistics such as reliability, average grade, and correlation for all quiz and question types.
To see the Assessment Quality Dashboard, you must be enrolled in the course offerings whose assessments you want to see. Quizzes need at least one attempt to be included in the dashboard.
A pop-up appears when you first access the Assessment Quality Dashboard that summarizes what displays in the default view. The Org Unit drop down filter includes a list of all courses in which a user is enrolled as Course Administrator. It also includes a search bar which can be used to search for a course or semester. You can dynamically add or remove courses by clicking the check box beside the org unit name.
The dashboard has 3 views: the landing page, the Quiz Item Analysis area, and the Preview Question area. The dashboard contains the following functionality:
In general, when using quiz and question statistics, it is important to keep in mind the sample size for the given quiz or question. Metrics increase in statistical relevance as the sample size increases.
The landing page shows you visualizations combining the data from all the quizzes that you manage. The data on this page enables you to analyze and identify quizzes that are underperforming in terms of grade scores and reliability.
Under Summary, there are cards for Results (the number of quizzes that you manage and meet the criteria applied to the dashboard), Average Score, Flagged Question (the number of quizzes with one or more questions that are outside the set threshold for acceptable values), and Quiz Reliability. You can turn these cards on and off and adjust the thresholds in Settings.
The Quiz Details area contains a dynamic table of quizzes that meet the criteria applied to the dashboard. An "!" icon appears next to quizzes that have one or more flagged questions. Click on any of the quizzes in this table to navigate to the Quiz Item Analysis page for that quiz.
If you want to compare multiple occurrences of the same quiz to see how the statistics vary, enter the name of the quiz in the search input above the quiz table. This applies a filter to the entire dashboard. Quizzes only display if their name matches your search, and courses only display if they contain a quiz whose name matches your search. The search input has truncation limits of 5,000 courses and 50,000 quizzes, so if you have access to a very large number of courses, we advise filtering by course prior to filtering by quiz name for best results.
The Quiz Details table includes the following:
Click on a quiz to navigate to the Quiz Item Analysis area, which provides a breakdown of each question in a quiz.
Click on Go to quiz under the name of the quiz, and the Edit Quiz page opens in a new window.
Under Summary, there are cards for Quiz Details which includes the details from the previous page, Low Mean which counts the number of quiz items with a mean lower than your threshold, High Deviation which counts the number of quiz items with a deviation greater than your threshold, Weak Correlation which counts the number of quiz items with a correlation lower than your threshold, and High Discrimination which counts the quiz items with a wide gap between low and high performers. You can turn these cards on and off and alter the thresholds in Settings.
The Quiz Items area contains a dynamic table of quiz items that meet the criteria applied to the dashboard. An "!" icon appears next to quizzes that have one or more statistics out of range of the set threshold. Click on any of the quiz items in this table to navigate to the Preview Question page for that quiz item.
The Quiz Items table displays statistics and details about each question in the quiz, including:
Click on a quiz question to navigate to the Preview Question area, where you can preview quiz questions, comments, and hints.
For all of the metrics on the Assessment Quality Dashboard, rounding is performed only once, at the end of the calculation. Different metrics have different numbers of final decimal places. If the digit in the final decimal place is followed by digit greater than or equal to 5, it is rounded up; if followed by a digit smaller than 5, it remains as-is.
For example, 1.2356 rounded to 2 decimal places becomes 1.24, while 1.2345 becomes 1.23.
