Hi @HopeLyon ...
As an instructor, you should be able to see this kind of information via New Analytics. Check out this Guide:
How do I view average course grade analytics in an... - Instructure Community - 1193 (canvaslms.com)
If you look at the image under the heading "Filter by Assignment", you'll see that chart has a bunch of blue dots. In your own course, you should hopefully have something similar. Click on a blue dot for an assignment within the chart, and a fly-out menu on the right side of your screen will appear. You'll see a smaller chart showing "Average Grade", "Low", and "High".
Do you think this information will be helpful for your needs?
Keep us posted herein the Community...thanks!
