Random Variables
Discrete random variables can
take on a countable value
(generally what you would think
of as whole numbers)
Also, make sure you know
the difference between discrete
and discreet. If a friend tells

Todays lab will show you how to generate r statistics (correlations) on your data. Remember that when
you compute correlations that you cannot assume causality, even if your r statistic is at or very close to +1
