ITPEC IP April 2023 — Question 100 of 100
Running two design variants in parallel and comparing their paid-service conversion rates is an A/B test. Users are divided between version A and version B, a predefined outcome is measured, and statistical comparison indicates which variant performs better. The variants should differ only in controlled ways so the result can be attributed to the tested change.
Answer (a)
Why not others:
- (b) ABC analysis ranks inventory or other items into importance classes
- (c) Cluster analysis groups observations by similarity without predefined labels
- (d) Regression testing checks that software changes have not broken previously working behavior
Key rule: A/B testing experimentally compares alternative user experiences using a measurable outcome such as clicks, registrations, or conversions.
