A/B/n Testing

Despite these additional variations, though, A/B/n testing works the same way as standard A/B testing.

A/B/n testing is the process of A/B testing with more than two different versions. The little “n” doesn’t refer to a third test, but to any number of additional tests: A/B/n encompasses A/B/C, A/B/C/D, or any other type of extended A/B test.

A/Bn testing is a matter of splitting users into groups, assign variations (typically of landing pages or other webpages) to groups, check the change of a key metric (typically conversion rate), check the test results for statistical significance, deploy the winning version.

A/B/n Testing vs. Multivariate Testing

Though they’re often confused, A/B/n testing is not the same as multivariate testing. The key difference lies in how the variations are controlled. Let’s use a webpage as an example. Say we have an image and a call to action (CTA) button, and we have three variations of each. If we run a multivariate test, it will automatically test all possible combinations — in this case, 6. However, if we run an A/B/n test, we hand-select which variations we want to test, which is frequently less than every possible combination. If we had a large number of different resources we wanted to test, the number of different variations in a multivariate test would grow exponentially — quickly requiring massive amounts of traffic and time it would take to get statistically significant results – but in an A/B/n test, we can manually choose how many variations to deploy.

Switch It On With Split

The Split Feature Data Platform™ gives you the confidence to move fast without breaking things. Set up feature flags and safely deploy to production, controlling who sees which features and when. Connect every flag to contextual data, so you can know if your features are making things better or worse and act without hesitation. Effortlessly conduct feature experiments like A/B tests without slowing down. Whether you’re looking to increase your releases, to decrease your MTTR, or to ignite your dev team without burning them out–Split is both a feature management platform and partnership to revolutionize the way the work gets done. Schedule a demo or explore our feature flag solution at your own pace to learn more.
