media_views.csv

The media view data refer to student interactions with the videos in the course. They come in a table of student-video cases. That is, there is a row for each video for each student, containing data that attempts to measure the student’s engagement with the video (how long spent watching, how many times, etc). Note that there aren’t many videos in these versions of the textbook.

Below is a description of each variable in the responses table. You can also download the description of media_views.csv (CSV, 3KB).
