See how SE Survey performs the calculation to obtain the scores of "Test" and "Survey" mode surveys with the "Allow score" option enabled:
Score calculation (Survey)
First, the question score is calculated. To do that, the score of the selected answer is divided by the maximum score of the answers to the question, generating a value between 0 and 1. Then, this value is multiplied by the weight of the question.
Examples:
Consider question "ABC", with weight of 1.0 and the following possibilities of related answers and scores:
▪Answer 1: 100.00 ▪Answer 2: 75.00 ▪Answer 3: 50.00 ▪Answer 4: 25.00
And the respondent has selected Answer 3.
|
Calculation - Question ABC
|
Consider question "XYZ", with weight of 2.0 and the following possibilities of related answers and scores:
▪Answer 1: 100.00 ▪Answer 2: 75.00 ▪Answer 3: 50.00 ▪Answer 4: 25.00
And the respondent has selected Answer 2.
|
Calculation - Question XYZ
|
Once done, the calculation to obtain the survey score consists of: [SUM(QUESTION SCORE CALCULATION) / SUM(QUESTION WEIGHTS)] * 10. Always converted to base 10, as the maximum score of the survey is 10.
Example:
Consider the "Survey 1" survey with questions ABC and XYZ, whose scores have been previously calculated:
Calculation - Survey 1
|
It is important to point out that only the questions that do not have the "Do not consider this question for the final score" option enabled will be considered in the calculation.
|
Score calculation (Test)
First, the question score is calculated. To do that, a correct answer is equivalent to 1, a wrong answer is equivalent to 0 and a partially correct answer may vary between 0 and 1 according to what was set in manual correction. Then, this value is multiplied by the weight of the question.
Examples:
Consider question "ABC", with weight of 60 and the following possibilities of answers:
▪Answer 1: 1 (Right) ▪Answer 2: 0 (Wrong)
And the respondent has selected Answer 1.
|
Calculation - Question ABC
|
Consider question "XYZ", with weight of 20 and the following possibilities of related answers and scores:
▪Answer 1: 1 (Right) ▪Answer 2: 0 (Wrong)
And the respondent has selected Answer 2.
|
Calculation - Question XYZ
|
Consider a "Descriptive" question, with weight of 40 and the following alternatives for the user who will perform the correction:
▪Correct answer: 1 ▪Wrong answer: 0 ▪Partially correct answer: 0.5
And the Partially correct answer has been selected.
|
Calculation - Descriptive Question
|
Once done, the calculation to obtain the final score of the survey consists of: [SUM(QUESTION SCORE CALCULATION) / SUM(QUESTION WEIGHTS)] * 10. Always converted to base 10, as the maximum score of the survey is 10.
Example:
Consider the "Test 1" survey with questions ABC, XYZ and Descriptive, whose scores have been previously calculated:
Calculation - Survey 1
|
It is important to point out that the calculation will only consider questions that:
▪Do not have the "Do not consider this question for the final score" option enabled; ▪Are not in sections with the "Do not take into account the questions of this section for the final score" option enabled (Test mode). |
