why bother and check for significant difference?
because you don't want to make decisions based on events that might be just a random coincidence...
OK, but how do i use it? is it simple?
Simply, add the total exposures and total success on each side (there is a picture near the video. a little hard to notice at first), and know (statistically) if one side did significantly better than the other.
(you may also choose different level of confidence, if your'e feeling geeky about it)
Want to start A/B testings, but don't know how?
feel free to contact me, I'd be happy to support.
Thanks for watching :)
