Proper statistical methodology is the foundation of reliable A/B testing. Using these calculators ensures your experiments have the necessary sample size to detect meaningful differences and helps you interpret results correctly.
Many optimization teams make critical errors by stopping tests too early or misinterpreting statistical significance. These tools, based on proven statistical methods similar to those developed by Evan Miller and other statisticians, help you avoid these pitfalls.
