Views report for Ubercart Order product totals for date range?
I found my answer. I used the Views Aggregator Plus module (https://www.drupal.org/project/views_aggregator). I applied "Group and Compress" and "Tally Members" in the "Group Aggregation" column within the Views Aggregator Table options for the SKU field, and I applied "Sum" in the "Column Aggregation" column for the Quantity field. This provided me with the exact result I was looking for.
