Exploratory cluster analysis between the student attributes in Table 1 for all courses, regardless of the availability of recordings (13,585 completely filled out surveys; attributes related to recordings are not part of this analysis, since not all students could have provided them).

The colors indicate clusters found in an exploratory analysis
