What is Logic in a Survey?

Published in Survey Design 3 mins read

Logic in a survey refers to the functionality that allows the survey's behavior to adapt dynamically based on the respondents' answers. This enables a more personalized and efficient survey experience.

How Survey Logic Works

Survey logic uses rules to control what a respondent sees and experiences based on their responses to previous questions. These rules can dictate:

  • Page Skipping: Directing respondents to specific sections or skipping irrelevant pages entirely.
  • Question Display: Showing or hiding particular questions based on prior answers.
  • Personalization: Modifying question wording or options based on respondent profiles.
  • Scoring and Branching: Assigning scores to answers and routing respondents to different paths.
  • Quota Management: Controlling the number of responses for specific demographic groups.
  • Automated Actions: Triggering notifications or updates based on responses.

Types of Survey Logic

Several types of logic can be implemented in a survey:

  • Skip Logic (Branching Logic): Allows respondents to skip questions or entire sections based on their previous answers. For example, if a respondent answers "No" to a question about owning a car, they would skip questions about car insurance.
  • Display Logic (Conditional Logic): Controls the visibility of questions or options based on previous answers. For instance, showing a follow-up question only if a specific answer is selected.
  • Scoring Logic: Assigns numerical values to responses, enabling the calculation of overall scores or categorizations.
  • Quota Logic: Limits the number of respondents in particular demographic groups to ensure representativeness in the sample.
  • Randomization Logic: Presents questions or answer options in a random order to minimize bias.

Examples of Survey Logic in Action

  • Example 1: Product Feedback: If a customer indicates they are unhappy with a product, the survey could immediately branch to a section asking for more detailed feedback on the specific issues encountered.
  • Example 2: Demographic Targeting: If a respondent indicates they are a student, the survey might present questions relevant to their academic experience.
  • Example 3: Health Questionnaire: Based on the answer to a question about smoking, the survey may show additional questions relating to smoking habits and health risks.

Benefits of Using Survey Logic

  • Improved Respondent Experience: Makes surveys more relevant and less time-consuming.
  • Higher Completion Rates: Reduces respondent fatigue and frustration.
  • More Accurate Data: Ensures respondents answer only questions that apply to them.
  • Efficient Data Collection: Streamlines the survey process.
  • Personalized Surveys: Creates a more engaging experience for respondents.

By using logic, you can create surveys that are more effective at gathering the data you need and providing a better experience for your respondents.
