The field of statistics is rich with
details and theory that cannot even begin to be touched in this unit. A true study of statistics and the interpretation
and comparison of data sets truly needs deeper treatment than what is given in this time-limited course. This unit begins
by introducing sigma notation. The basic measures of central tendency and dispersion are then reviewed. The new
concept of standard deviation is then introduced and used within the context of normally distributed populations.
