Welcome to Sample size calculation — level II
Sample size calculation — level II is an interactive, self-paced course that teaches you the fundamental concepts of how to calculate the required sample size for experiments.
In this second course, you will build on the knowledge you gained in the first course and learn how to calculate the sample size for more complex experiments. You will learn how to combine the results from many metrics into one decision. You will learn how the number of success metrics, guardrail metrics, and number of comparisons affect the sample size.
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.
Before you begin
This is the second level of the sample size calculation course. If you haven't already, start with Sample size calculation - level I to build a solid foundation in hypothesis testing and sample size calculation.
Lessons
This course consists of the following lessons:
Lesson 1: Multi-metric decision making
Learn how to combine the results from many metrics into one decision while managing risks.
Lesson 2: Number of success metrics
Build intuition for how the number of success metrics affects the sample size.
Lesson 3: Number of guardrail metrics
Understand why guardrail metrics affect the sample size different from success metrics.
Lesson 4: Number of comparisons
Learn how the number of treatment groups and comparisons affects the sample size.
Lesson 5: Sample size calculation playground - Level II
Build intuition for sample size calculation by playing with different settings in the playground.
