Calculation_int Decaying Average? Outcomes Import

[Jul_Cro]

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
