Write an Effective Hypothesis


Your experiment is only as good as your hypothesis. With a well-crafted hypothesis, you establish your problem, solution, and your expected results, establishing a context that you can analyze when your experiment is complete. It acts as a throughline you can use to connect your last experiment to this one, and this experiment to the next, scaffolding your experiments over time into a truly effective optimization program.

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

  1. What impact can a specific, evidence-based hypothesis have on an experiment’s effectiveness?
  2. How do you link a hypothesis to business goals?
  3. How can a hypothesis help you effectively leverage experiment results?
  4. What are the elements of a hypothesis?
