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.

QuestionTips Rotate 1.jpg

  • I want to show the answer options in random order (except None of the above option)

QuestionTips Randomize 2.jpg

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 Note: quest.randomizeAnswerOptions(randomSeed, startIndex, endIndex): randomize answer options in a range specified by startIndex and endIndex, the order is unique for each randomSeed
