    Sample Size Question

    Alexis D'Alba

      Hi there!

       

      I'd love to better understand if the approach i'm taking to find out our sample size for a/b testing is correct. Any insights are much appreciated!

       

      I've plugged in the following numbers in sample size calculator:

       

      Confidence level = 95%

      Confidence Interval = 5

      Population = 17K

      Sample size = 376

       

      I then divided 376/ 17, 000 = 22%

      I doubled that number to make up my sample size, which equals 44%.

       

      So, my test group was 44% and then the winner to 56%
