Why are carrying over variables useful?
Carrying over variables from one survey reduces respondent burden by not re-asking questions about stable information like demographics. It also improves efficiency and data quality by reusing reliable information already collected.
In BlockSurvey, carrying over variables and their data between forms or surveys is easy.
This guide will walk you through the process of using a simple two-part survey example.
Example Scenario
You’re conducting a two-part survey. In the first survey, you gather the participant’s name and email. In the second survey, you use their email to personalize the survey and track responses.
Step-by-Step Guide
Create the First Survey: Collect user information, including their name and email.
Create the Second Survey: Design this follow-up survey to include questions that will use the email collected in the first survey.
Set Up Variables
In both surveys, navigate to Settings > Assignment & Formulas > Text Variables.
Create identical variables in both surveys for consistent data handling.
Configure the Redirect
Publish the second survey and copy its URL.
In the first survey, go to the Submit > Redirect Logic tab.
Paste the URL of the second survey and append the variables as query parameters in the URL.
Test the Setup
Publish the first survey.
Submit a test response to ensure data is carried over correctly before sharing the survey with respondents.
By following these steps, you can efficiently carry over variables between surveys to streamline data collection and enhance personalization.
