In the context of A/B testing experiments, statistical significance is **how likely **it is that the difference between your experimentâ€™s baseline version and test version isnâ€™t due to **error or random chance**. Statistical significance depends on 2 variables:

The number of sessions.

The number of conversions for both baseline and variant experiences.

A successful A/B test answers the question of how confident you are in the results. For example, if you run a test with a 95% significance level, you can be 95% confident that the differences are real.

In our A/B testing dashboard, you can view the statistical significance details of the testing experience by clicking on the *3 dots* in the far right of the experience, and selecting "*View Statistical Significance Details*". From there, a pop-up on the right will appear showing a breakdown of the Weight, Conversion Rate, Traffic (Sessions Served), Current Significance, and Required Sessions To Achieve % Significance.
