Review Scoring Method
Slayte uses a method called Weighted Average of Mapped Socores which allows the administrator to chose how much impact will a question have on the final score of the review.
With this method the scores from each question are first normalized to a 0-1 scale and then multiplied by their respective weights. The overall score is the average of these weighted scores.
For example:
If the review has 5 questions with the following scoring options, all with a Weighted score of 1:
- Question 1: 0 to 15
- Question 2: 0 to 10
- Question 3: 0 to 20
- Question 4: 0 to 35
- Question 5: 0 to 20
And the results obtained were:
- Q1: 10/15
- Q2: 7/10
- Q3: 12/20
- Q4: 29/35
- Q5: 17/20
The calculation for the result is:
((10-0)/(15-0)*1+(7-0)/(10-0)*1+(12-0)/(20-0)*1+(29-0)/(35-0)*1+(17-0)/(20-0)*1)/(1+1+1+1+1) = 72.91%One of the advantages is that the weights of the questions can be adjusted to show the sum of the "points" obtained on each question meaning that the end result will be equal to that of adding each score up.
Example:
Using the same 5 questions as the example before, but now changing the weight of each to that of the maximum value of the question:
- Question 1: 0 to 15, weight = 15
- Question 2: 0 to 10, weight = 10
- Question 3: 0 to 20, weight = 20
- Question 4: 0 to 35, weight = 35
- Question 5: 0 to 20, weight = 20
And with the same results as before:
- Q1: 10/15
- Q2: 7/10
- Q3: 12/20
- Q4: 29/35
- Q5: 17/20
The calculation for the result is:
((10-0)/(15-0)*15+(7-0)/(10-0)*10+(12-0)/(20-0)*20+(29-0)/(35-0)*35+(17-0)/(20-0)*20)/(15+10+20+35+20) = 75.00
