Question: True or false: The "independent variable" in an A/B test is the control or the variation that remains unchanged.
- True
- False
Explanation
An A/B test needs one stable baseline so performance differences can be attributed to the tested change. The control provides the unchanged version for comparison against the variation. Keeping other elements consistent helps isolate the impact of the test condition. This structure supports reliable optimization because results are tied to a defined variable rather than multiple simultaneous changes.
Why the other options are incorrect
False is incorrect because the test requires an unchanged comparison point to evaluate the variation.
