An A/B Test is a common and effective practice to randomly present different versions of your survey to learn more about how these changes ultimately affected responses. You can test whether the modification of a variable, such as text or image, will significantly impact the results.
Surveyol will randomly assign each respondent to be shown one of the test variables you defined. The A/B split test can be set at any percentage (as long as they total 100%). It is, however, always a wise decision to collect at least 50 responses for each variable to ensure you can conclude there are significant differences from one segment to another.
When you include A/B test questions in your survey, you have the option to filter your survey results by A/B test under the "Results" section. Please refer to the article How to filter survey results?
