Sample Ratio Mismatch (SRM) Calculator for A/B Testing
The SRM calculator helps detect issues in A/B testing experiments by analyzing traffic distribution between test groups. It uses chi-squared statistics to identify statistical anomalies that may affect test validity.
This tool is essential for data specialists, analysts, and marketers who need to ensure the integrity of their A/B tests. It helps identify when traffic distribution deviates from expected proportions.
The calculator provides clear interpretation of results with color-coded status indicators, making it easy to understand when intervention is needed to maintain test quality.
