# Setting Statistical Analysis Plan Defaults for Experiments

## What is the Statistical Analysis Plan?â€‹

The Statistical Analysis Plan determines the statistical methods used to analyze your experiments.

**Confidence Interval Method**: Sequential, Fixed Sample, Bayesian**Confidence Level**: The percent of time the confidence interval contains the true lift**Desired Power (for the progress bar)**: The percent of the time the minimum effect size will be detected, assuming it exists.

## How to Change the Defaultsâ€‹

You can define the defaults for the statistical methods used for experiments across Eppo by going to **Admin > Settings > Statistical Analyis Plan**.

The settings defined at the Admin level will be the company-wide defaults for any â€śdraftâ€ť, â€śrunningâ€ť, and â€śwrap upâ€ť experiments that have not opted out of using the defaults. Individual experiments can choose to opt out of the company-wide defaults and use different settings. See how to set the statistical analysis plan at the experiment level.
