When configuring a score set for Scoring, you will be prompted to select whether the final score will be calculated by 'Sum' or 'Mean'.
Put simply, 'Sum' calculation is the total of all criteria together. 'Mean' calculation takes things one step further by dividing the total by the number of criteria. To better illustrate this, check out the example below.
|Criteria 1: 5/10 points||Criteria 1: 5/10 points|
|Criteria 2: 7/10 points||Criteria 2: 7/10 points|
|Criteria 3: 9/10 points||Criteria 3: 9/10 points|
|Total score = 21/30 points||Total score = 7/10 points|
|Formula: (5 + 7 + 9 = 21)||Formula: (5 + 7 + 9 = 21 / 3 criteria = 7)|
The same calculations can also be applied to criteria with differing weights.
'Sum' and 'Mean' calculations do not affect the leaderboard.
The leaderboard will always show the average score of each application— it's the 'score out of' part which changes.
With sum, it will be out of the total of all criteria.
With mean, it will be out of the average of all criteria.
