Notations
---------------
This page was inspired from the following `Wikipedia page <https://en.wikipedia.org/wiki/Notation_in_probability_and_statistics>`_.
Sample and Population
=====================
A *population* is the entire population that you want to analyze. It is a exhaustive set. A *sample* is a subset of the population. It is a non-exhaustive set.
.. note::
TODO add figure
*Statistics* allows you to infers properties on a population using samples with a certain degree of confidence.
Notation: A Schizophrenia story
================================
Two different notation conventions are used. The one to use depends if you are working on a *population* or a *sample*:

* - Sample mean
- :math:`\mu`
- :math:`\overline{x}`
