Welcome to Sample size calculation — level III
Sample size calculation — level III is an asynchronous, interactive, self-paced course that teaches you the fundamental concepts of how to calculate the required sample size for experiments. This course focuses on building intuition for why you need to plan the sample size before the experiment and what settings and aspects that affect the required sample size.
In this course, you'll learn about some of the more mathematical aspects of sample size calculation. You learn about variance reduction and how it reduces the required sample size. You also get to build intuition for how the sample size calculation differs between binary and continuous metrics, and how the treatment group proportions affect the required sample size. Finally, you get to play around with the complete sample size calculator, accounting for all the aspects covered in all three sample size courses.
There are quiz questions throughout the course to help you check your understanding of the material. Complete each lesson's questions to track your progress.

Lessons
This course consists of the following lessons:
Lesson 1: Binary metrics
Understand how sample size calculations differ between binary and continuous metrics.
Lesson 2: Treatment group proportions
Build intuition for why the relative sizes of the treatment groups affect the required sample size.
Lesson 3: Variance Reduction
Learn why variance reduction might as well be called sample size reduction.
Lesson 4: Sample size playground
Build intuition for sample size calculation by playing with different settings in the playground.
