Randomize answer options/sub questions
In order to synchronize randomization of sub questions/answer options among several questions
As a questionnaire creator
I want to control the randomization with a random seed, which means that the system will generate a unique order based on one value of random seed
Randomize answer options
Example
- I have a single question with drinks as answer options.
- I want to show the answer options in random order (except None of the above option)
Solution
Use any random seed and a randomization range from 0 to 5
Code
- Add a Single question to Questionnaire editor
- Go to menu Properties -> Question scripts -> Java script and input below script
quest.randomizeAnswerOptions(3, 0, 5);
Note: quest.randomizeAnswerOptions(randomSeed, startIndex, endIndex): randomize answer options in a range specified by startIndex and endIndex, the order is unique for each randomSeed
Randomize sub questions
Example
- I have a single grid question with drinks as sub questions.
- I want to show the sub questions in random order
Solution
Use any random seed and a randomization range from 0 to 5
Code
- Add a Single question to Questionnaire editor
- Go to menu Properties -> Question scripts -> Java script and input below script
quest.randomizeSubQuestions(3, 0, 5);
Note: quest.randomizeSubQuestions(randomSeed, startIndex, endIndex):randomize sub questions in a range specified by startIndex and endIndex, the order is unique for each randomSeed
