A Sample Ratio Mismatch (SRM) Checker is an application that helps you in validating the ratio of two samples that are taken from the same distribution. It is designed to be used as an A/B test for your website, but can also be used for other applications.

What is SRM Checker?

It is a Chrome application that is used to check if your data follows the expected distribution. If your data is not following the expected distribution, you have two options. You can either:

Use the Checker to identify if the observed sample count is more or less than the expected one. If the observed sample count is greater than the expected one, this means that there is a potential for Sample Ratio Mismatch (SRM). Use the Checker to find out if the differences between the expected and the observed sample proportions are greater than the acceptable limit.
