What does the field "calculation_int" refer to with a decaying average method in the Outcomes csv import? The instructions allow an integer 1-99 but I am not understanding what that means.
Thanks for your help!

The Decaying Average calculation weights the last attempt at a specific percentage of the overall calculation, with all other attempts making up the final weight. You define that weight when you create the outcome. Canvas defaults to a 65% last attempt, 35% all others. Here's an example:
On a 4 point rubric, a student has 5 attempts:
Attempt | 1 | 2 | 3 | 4 | 5 |
---|---|---|---|---|---|
Score | 2 | 2 | 3 | 2 | 4 |
Depending on how you weight your averages, a student score could be:
Weight (last/others) | Calculation | Score |
---|---|---|
65/35 (default) | ( [ (2+2+3+2) /4 ] * 0.35) + ( 4 * 0.65 ) | .79 + 2.6 = 3.39 |
50/50 | ( [ (2+2+3+2) /4 ] * 0.5) + ( 4 * 0.5 ) | 1.13 + 2 = 3.13 |
35/65 | ( [ (2+2+3+2) /4 ] * 0.65) + ( 4 * 0.35 ) | 1.46 + 1.4 = 2.86 |
