17 Statistical Hypothesis Tests in Python (Cheat Sheet)

Last Updated on November 28, 2019

Quick-reference guide to the 17 statistical hypothesis tests that you need in
applied machine learning, with sample code in Python.

Although there are hundreds of statistical hypothesis tests that you could use, there is only a small subset that you may need to use in a machine learning project.

In this post, you will discover a cheat sheet for the most popular statistical hypothesis tests for a machine learning project with examples using the Python API.

Each statistical test is presented in a consistent way, including:

  • The name of the test.
  • What the test is checking.
  • The key assumptions of the test.
  • How the test result is interpreted.
  • Python API for using the test.

Note, when it comes to assumptions such as the expected distribution of data or sample size, the results of a given test are likely to degrade gracefully rather than become immediately unusable if an assumption is violated.

Generally, data samples need to be representative of the domain and large enough to expose their distribution to analysis.

In some cases, the data can be corrected to meet the assumptions, such as correcting a nearly normal distribution to be normal by
