Power analysis is a statistical analysis based on significance level, effect size, statistical power, and sample size. We can use it to calculate any one of the four values given the other three. Power analysis and sample size calculation are common interview questions for data analyst, data scientist, and machine learning engineer positions.
In this tutorial, You will learn:
👉 What are significance level, effect size, statistical power, and sample size?
👉 How to calculate the sample size for hypothesis testing (AB testing) using Python?
👉 How to calculate the statistical power?
👉 How to calculate the minimum detectable effect size?
👉 How to calculate the significance level?
👉 How do sample size, significance level, and effect size impact the statistical power?
