ITPEC IP October 2025 — Question 100 of 100
An A/B test runs two variants in parallel and compares a measured user outcome — here the outcome is the rate of applications for paid service.
Users are divided between the conventional design and the new design under comparable conditions. Statistical comparison of conversion rates shows which design performs better while reducing the influence of time, traffic mix, and unrelated changes.
Answer (a)
Why not others:
- (b) ABC analysis ranks inventory or other items by value or importance
- (c) Cluster analysis groups observations by similarity without predefined labels
- (d) Regression testing checks that software changes have not broken existing behavior
Key rule: Use A/B testing for controlled comparison of alternative experiences against a defined metric such as clicks, sign-ups, purchases, or retention.
