Incorrect join in data tables causing incorrect average for Average Days Since Last Interaction


This behavior has been resolved and deployed to the production environment as of 10/9/23.


The current calcuation for Average Days Since Last Interaction, in the Student tab of Admin Analytics, is incorrectly calculating the days since last interaction for each student in each course.

It should be calculating the average based on the days since a student’s last interaction in Canvas (across all of that student’s courses).

Expected Behavior

Average days since last interaction is an average of the the last days since last interaction for each student (across the courses that are relevant to selected filters)


No workaround exists at this time.

Steps to Reproduce

Not available at this time.
