Some references that I found to be particularly helpful:

Is this really free

Yes - the calculator is a free service provided by A-B.Tools. Please also note that we care deeply about your privacy and thus do not track/log/process any information you enter into the calculator. For more details see our Privacy Policy.

What is an A/B Test?

To evaluate the impact of new features, many websites and apps conduct controlled experiments on their users. Oftentimes these experiments involve changing some part of the user-interface, such as choosing a different headline or using different colors (here's one example from Netflix). Crucially however, only some users get to see the updated version while for the rest there is no change at all. Having separated the users in such a manner, the impact of the change is then evaluated by comparing the behavior of the two user groups along key-performance indicators such as clicks or conversions. Finally, a verdict is passed and whichever version works best becomes the new default version and is presented to all users.

Are those questions really frequently asked?

No. However I don't think they're irrelevant either. And maybe everyone looking for answers to these questions already found the answer here in which case there is no point in asking. If you have any more questions feel free get in touch via e-mail
