## What is sample size?

The same size calculator calculates what sample size per variant you'll need to measure the
desired
change in your conversion rate for your A/B test. The calculator uses the baseline
conversion rate for
your control group, the minimum relative change in conversion rate you would like to be able
to detect
(MDE), and a significance threshold (95% by default).

By using this calculator before your A/B tests, you'll be able to estimate the duration of
your A/B test
according to how many vistors you get on a daily basis.
