Taskforce Mart - Level 2 Course Weekly Distribution Summary
The mart_taskforce.level2_course_weekly_distribution_summary mart aggregates data about a course's performance and activities each week and describes the activity distribution. The schema for this mart largely mirrors that of mart_taskforce.level1_aggregated and mart_taskforce.level2_aggregated; however, this mart gives averages and standard deviations for each field. Questions about "what the average student" is doing in a course can be answered with this mart.

The following visualization shows the construction of this data mart defined in the UDP marts repository. More information on the repository and diagram can be found on this marts page.

This level 2 table has many fields, so we’ve grouped them together in the following subcategories:
- Assignments
- Submissions
- Assignments
- Missing Assignments
- Late Submissions
- Submission Time Buffer
- Published Scores
- Discussions
- Discussion Threads
- Discussion Entries
- Learning Environment Activity
- View days
- Sessions
- Tool Launches
- File Views
The only dependency for this mart is the mart_taskforce.level1_aggregated. All calculations and fields are based on that mart, and there are no direct dependencies to the UDP itself. As long as the mart_taskforce.level1_aggregated is successfully created, this mart can also be created.
Many fields have names that include tiny, small, medium, large, and major. These classifications are based on the group_weight field in the ‘learner_activity_group’ entity. The cases are as follows:
- If the group_weight is null or equal to 0%, the submission is ‘unweighted’.
- If the group_weight is less than or equal to 2%, the submission is ‘tiny’.
- If the group_weight is greater than 2% and less than or equal to 5%, the submission is ‘small’.
- If the group_weight is greater than 5% and less than or equal to 10%, the submission is ‘medium’.
- If the group_weight is greater than 10% and less than or equal to 25%, the submission is ‘large’.
- If the group_weight is greater than 25%, the submission is ‘major’.
These assignment weight groupings are consistent with the groupings for the Level 1 mart.
The majority of the schema for mart_taskforce.level2_aggregated are averages and standard deviations based on the distribution of corresponding fields per-course, per-week in mart_taskforce.level1_aggregated. The corresponding table mart_taskforce.level2_aggregated applies these averages and standard deviations (per-course, per-week) for each student and produces z-scores accordingly.
