Control Size: 3,845 | Test Size: 3,845 |
The expected conversion rate of the control group. This can be obtained through a monitoring campaign or checking the historical data. |
|
The minimum relative change in conversion rate you would like to be able to detect. Given a 10% baseline conversion rate and a 20% MDE, the minimum conversion rate of the test group you would like to be able to detect is 10% * (1 + 20%), i.e. 12%. | |
The proportion of the sample to include in the control group. |
The probability of the test rejecting the null hypothesis (H0) when it is true. | |
The probability of the test rejecting the null hypothesis (H0) when the alternative hypothesis (H1) is true. |
