Hypothesis tests

Statistical hypothesis tests are used to decide whether data sufficiently support a particular hypothesis. SciPy defines a number of hypothesis tests, listed in Hypothesis Tests and related functions.

You can find simple examples to each test in the corresponding docstring. For more detailed examples, see the following sections.
