How to Keep the same randomization order of answers/topics for several questions

Overview

A common survey requirement is to display a set of answer options in a randomized order. In some cases, multiple questions share the same answer list, and you may want the answers to appear in the same randomized order across all of those questions.

This guide demonstrates how to implement this behavior in SurveyToGo, ensuring that the answer options are randomized once and then displayed in the same order wherever they are used throughout the survey.

 

Step 1: Create a Dummy Open Ended Question

Add an open ended question to the script, and set it to be hidden from surveyor.

The purposes of this question would be to save a string of the answers set indexes in the chosen randomized order:

 

Step 2: Determine the randomized order

Add the following code to the first question’s (out of the questions to display…) start script:

 

if (!Answered(QRef(1)))
{

     // create array of all answers indexes in a randomized order
     var arr=CreateRandomArray(GetAnswerCount(CurrQues));
     // set the string of the indexes randomized order in the dummy question
     SetAnswer(QRef(1),IntArrayToString(arr));
}

 

Step 3: Add the randomization code to all questions

In all displayed questions’ start script, add this code:

RandomizeAnswers(CurrQues,StringToIntArray(Answer(QRef(1)).ToString()));
