# 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.

#### Dependencies

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.

#### Assignment Weight Groupings

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.

#### Average and Standard Deviation Fields

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.

For this mart, we define sessions using three different time cutoffs: 10 minutes, 20 minutes, and 30 minutes. We define the time spent in a session by adding up the duration of events in the session. These fields describe the distributions for the number of sessions, total time spent, total number of actions, average time spent, and average number of actions for all three time cutoffs for a student in a course for a given week in the term. The definitions of the base session, time, and action fields exist in the documentation for *mart_taskforce.level1_aggregated.*

Please visit our separate interaction session mart documentation page here for a visual example and more information about interaction sessions too.

#### Tool Launches

**Fields**

Description

These fields describe the distributions of the LTI tools launched by students in the learning environment of a course for each week in the term. More detailed definitions of LTI launches exist in the documentation for *mart_taskforce.level1_aggregated.*

The launch_app_name and total_tool_launches are unique to this table. Launch_app_name is of type ARRAY<STRING>, and total_tool_launches is of type ARRAY<INTEGER>. The launch_app_names and total_tool_launches values correspond and represent the total launches for each tool by all students in the course for the week.
