Display relevant statistics directly in the Gradebook
Currently, the Gradebook (GB) displays no statistical information about class performance. This seems like the most relevant place to put such information. Examples of missing information that seemed useful to me include:
- Display the mean, stdev, high score, low score, # late, # missing, etc of each graded item at the bottom of every column
- Display the due dates and available dates for each graded item, probably at the top under the assignment title
- Clicking on an assignment title (or the little drop down menu) could bring up a histogram of student scores for that assignment, with customizable bin count
The stats calculated should be sensitive to the current filter settings. That is, if I'm only looking at grades for Section 4, then my averages should only be computed for that section.
This suggestion goes under my general viewpoint that the GB "tries to look and act like a spreadsheet, but doesn't really act like a spreadsheet". Things you would expect it to do, it just can't do.
