Dear @Ramya_SR ,

Guess we already had this discussion, however, let me ask you a few questions.

Where are you seeing this 'sample size mismatch' error/insight? Are you using some other tool to analyze this? If yes, kindly let me know.

Besides, check out this discussion as well.

Hi Pratheep,


We used cookie drop for target setup. Only Adobe Target was assigned for reporting. This target cookie was tagged to analyse data in adobe analytics. So when calculating confidence using AB test guide , it alerted SRM.



Although our intention might have been for the test to have a 50/50 split, if the actual split turned out to be different, like 45/55 or 40/60, could we still extract valuable insights to inform business decisions? Is it valid to disregard results just because there's uneven distribution, especially if there's sufficient traffic experiencing each variant?


Your insights on this topic is highly appreciated
