How it Works
1
Input Your Data
Enter the number of visitors and conversions for both your control (A) and challenger (B) variations. Get these numbers from your analytics or A/B testing platform.
2
Statistical Calculation
The tool computes conversion rates, pooled standard error, and a two-tailed Z-score. It then calculates the p-value using the standard normal cumulative distribution function at a 95% confidence level.
3
Interpret Your Results
See whether your result is statistically significant, view the confidence level, uplift percentage, and precise p-value. Make data-driven decisions with confidence.
