to calculate the mean, maximum and other statistical values, how
to perform various statistical tests, how to determine the confi-
dence interval, and how to produce a distribution of statistical
data. It also tells you how to perform regression calculations.

• This chapter contains a number of graph screen shots. In each case, new
data values were input in order to highlight the particular characteristics of
the graph being drawn. Note that when you try to draw a similar graph, the
unit uses data values that you have input using the List function. Because of
this, the graphs that appears on the screen when you perform a graphing
operation will probably differ somewhat from those shown in this manual.
