Experiment Group Configurations

Experiment Group Configurations#

Tags: educator reference

The edX Platform assigns learners to each experiment group in a group configuration.

Experiment group assignments have the following characteristics.

  • Dynamic

    The edX Platform assigns a learner to an experiment group the first time he or she views a content experiment that uses the group configuration.

  • Random

    You cannot control which learners are assigned to which experiment group.

  • Evenly distributed

    The edX Platform keeps track of the size of experiment groups, and assigns new learners to groups evenly. For example, if you have two experiment groups in a configuration, each group includes 50% of the learners in the course; if you have four experiment groups, each group includes 25% of the learners.

  • Permanent

    Learners remain in their assigned experiment groups regardless of how many content experiments you set up that use the same group configuration.
