Simple statistical parameters
Our first practical analyses of data involve measuring some of the fundamental statistical
parameters. These can be calculated without any knowledge of what the underlying
probability distribution might be. However, if we do consider the underlying distribution
these sample-based parameters will be estimates for their probabilistic equivalents. The
theory regarding whether we are truly estimating the underlying probabilistic parameters
in an unbiased way is left to further reading. Here we will simply introduce the simple
statistical parameters and how we usually calculate them.
