What is another name for an A/B test?

• A. A model-based test
• B. A split test or bucket test
• C. A dual-scenario test
• D. A sequential test

Answer: (B)

The idea being tested is comparing two versions by randomly assigning users to each version and seeing which performs better. Another name for that approach is a split test or bucket test, because you divide the audience into two groups (buckets) and run each variant in parallel to compare results. The terms don’t fit as well: a model-based test implies reliance on a specific statistical model rather than straightforward randomized comparison; a dual-scenario test isn’t a standard term used for this practice; and a sequential test involves testing one variant after another over time, which can introduce time-based confounding and isn’t the same as a parallel A/B comparison. So split test or bucket test best captures the practice.
