Define the statistical plots as box plots
Once you have entered the lists, you can examine the data using several different types of
statistical plots. First, look at the two forms of box plots.
To Do This Press Display
1. Go to the
STAT PLOTS
screen.
Note:
The TI
83 Plus lets you define up
to three different stat plots.
\
2. Turn on
Plot1
and define it as a
ModBoxplot
(
·
) of the male heart
rates.
Note:
ModBoxplot
graphs the outliers
(data more than 1.5 times the difference
between the third quartile [Q3] and the
first quartile [Q1] ) as points rather than
as part of the box.
