26.3    Statistical Calculations: statistics

The statistics module of the standard library contains several useful functions that perform simple statistical calculations.

The functions contained in the statistics module usually operate on a sample, an iterable object that iterates through numeric values. An example of a sample consisting of 10 floats could look as follows:

>>> data = [1.0, 2.0, 2.0, 5.7, 7.0, 1.1, 4.0, 2.0, 6.5, 1.5]  

Basically, a sample for use with the statistics module can contain integers, floats, and the decimal and fraction data types from the decimal and fractions modules.

Note

A sample should always consist of instances of a single data type; otherwise, the functions implemented in statistics might show undefined behavior. ...
