Optimization Statistics


Statistics are the cornerstone of every metric in business. Understanding how they're accumulated and how they work, even when you have an engine that does it for you, equips you with knowledge that can inform the way you build experiments. A basic understanding of how statistics are calculated and where they're drawn from will help you build more effective experiments and more realistically estimate how long it will take to see results.

In this course, you'll learn how to answer the following questions:

  1. What is statistical significance and how does Optimizely guarantee results?
  2. What do I need to know about the stats engine?
