Setting Statistical Analysis Plan Defaults for Experiments

What is the Statistical Analysis Plan?

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 Defaults

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 “draft”, “running”, and “wrap up” 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.
