Plan a new test

Plan the sample size you need for an A/B marketing test.

1. Enter the response rate you normally achieve. This can be the open, click or conversion percentage rate. Enter a value 00.00 to 100.00.
2. Enter the percentage improvement on the normal response rate you expect and wish to detect as statistically significant. For example, if your normal click rate is 20%, then entering 10 means the sample size will be calculated for a 10% improvement giving the improved click rate of 22%

The smaller the detectable percentage improvement sought the larger the sample size that will be required.
