Hi everyone,
I have noticed that natural aggregation calculates scales starting from 1, while mean of grades and weighted mean of grades start from 0.
For example in the custom scale: Good - Great - Excellent
- Natural aggregation awards: 1 - 2 - 3 points for each level.
- Weighted mean of grades and Mean of grades award: 0 - 1.5 - 3 points for each level.
Being used to the older aggregation methods (mean of grade and weighted mean of grade) as well as the way Rubrics are set (starting with 0 points) I was expecting Natural weight to start with 0 points too.
If the aim is to simplify the Gradebook, using only the Natural aggregation shouldn't they treat scales in the same way?
Quoting Natural weighting documentation:
"Natural weighting without custom weights corresponds to Sum of grades and simple weighted mean (SWM). Natural weighting with custom weights corresponds to Weighted mean of grades."
Thank you!
Anna
