The Minimum Detectable Effect (MDE): Ensuring Statistical Significance

The Minimum Detectable Effect (MDE) represents the smallest effect size, or the minimum change in your key metric, that your experiment is designed to reliably detect. Put simply, it’s the threshold of change that you can confidently attribute to the changes you’ve implemented in your experiment, rather than attributing it to the inherent variability of random chance. Understanding and defining the MDE allows you to establish a clear benchmark for success, ensuring that your experiment is capable of discerning meaningful changes from statistical noise.

By determining the MDE, you are assessing the statistical power of your experiment, which is its ability to detect a true effect if one exists. If your experiment lacks sufficient power to detect a meaningful change, you run the significant risk of wasting valuable time, resources, and effort on a test that ultimately yields inconclusive or misleading results. This pre-experiment calculation allows you to fine-tune your experimental design, adjust sample sizes, and optimize your testing parameters, ultimately maximizing the likelihood of obtaining statistically sound and actionable insights.

Optimizely provides tools and resources to help you calculate the MDE for your experiments, ensuring that your tests are designed for success.
