We're running an A/B/C test and trying to determine how to use the sample size calculator properly. We will stick with the recommended 95% confidence level and 80% statistical power, and we have 3 offers (including control). But little confused on baseline conversion rate and daily visitors.
Our test is showing 2 different product groupings on a specific page (vs. the control). Ultimately, we're trying to drive as much revenue (this is our success metric; normalizing metric in A4T is unique visitors) as possible, so we're running the test to determine which product grouping drives the highest revenue.
So in this case, should total number of daily visitors be.
And should baseline conversion rate just be whatever our normal conversion rate (orders/visits) for the overall site? Or something else or more specific?
