What is looping logic in surveys?

Surveys sometimes need you to repeat certain questions for the answer option provided in the previous question. For such a requirement we have looping logic. With looping logic you can iterate through the answer options for the same question. Meaning, you can ask the same question or questions multiple times depending on the answer options. 

Looping logic is helpful when you have one or even more follow up questions for one multiple choice question. When you set a looping logic for a particular question, a page break is inserted automatically which is necessary for branching so that it is understood that the loop is ended. In case of multiple follow up questions, you can set looping logic at the last question to identify the end of the loop. 

To ensure logic flow, you should make sure that all the follow up questions point towards that one multiple choice question, based on options of which the other questions are derived. This is called branching logic and the default branching of a question can be any other question, page or termination of the survey.

Example of looping logic

Looping logic and data analysis

When we think about the data we get from looping logic surveys, we will have multiple rows for a single response of a single respondent. This is due to branching. It is saved in the system as one row for one loop.so, while exporting the survey data to any other statistical packages, ensure the format at both ends is one and compatible. 

If you face any trouble with multiple rows for one response, you can also set a different question for selected answer options.

Where to use looping logic in a survey?

  • Course evaluation surveys – these are the surveys conducted in universities and academic institutes asking students to rate their courses and share feedback. They can have one question asking for them to select all the courses they applied for and then have follow up questions for the same selected options. 
  • Customer feedback surveys – these surveys ask the customers about the products they have used. Based on the options they select in the first question, the business can ask them certain follow up questions regarding the durability, ease of use, and performance of the products.

Advantages of looping logic

  • Using looping logic to branch the main question and link to the next follow up question will reduce the size of the survey. The questionnaire becomes concise.
  • With looping logic, you do not have to frame tons of questions for each and every answer option. This takes lesser programming time in case of multiple follow up questions.
