In How Do I View Course Analytics, among the "user actions [that] will generate analytics course participation" are posting comments to Discussions and submitting Quizzes. Currently my Spring '18 course has had two assignments: a quiz and a discussion (the discussion asks for a minimum of three posts). When I look at the snapshot of "participation", though, it doesn't match actual activity. In the screenshot below, students #1 and #3 have "participated" three times, though all they have submitted is one quiz. Students #2, #4, and #5 have all submitted a quiz and three posts to a discussion. My question is, what is Canvas counting as "participation" and why isn't it reading all student activity the same way?
