Reducing categories using outcome

Previously, we determined the proportions of discipline infractions for all 12 grade levels. We can create a data table, dgr_prop, containing these grade proportions mapping with grade and proportion columns. The proportions correspond to a student receiving disciplinary action during that grade.
