I have a client that wants to test 3 pricing options to visitors of a website. All options are for the same product and service (no difference except pricing). Their current idea is to present all 3 options to visitors and use conversions to determine which is the right pricing model for their business.
I'm more familiar with split testing, and even then I don't have any experience designing tests outside of interfaces like Optimizely. I'd really like to understand this style of test better, and figure out how to determine the requisite sample size to achieve significant results.
Is there a name for this sort of test? What differences should I be aware of between an A/B test and this scenario?
