# abtester

A web application that helps you design and evaluate the results of A/B tests.

[![Overview](https://github.com/gabrieltempass/abtester/raw/main/images/overview.png)](https://abtester.app)

### Calculate the ideal sample size

Samples too small may lead to inconclusive results,

while too large may have unnecessary costs and risks.

Find the right size with abtester.

### Analyze the statistical significance

In a properly designed A/B test, a difference between the groups is either due to a real effect or to random chance. Calculate the probability of each case and if the difference is statistically significant.
