Boxplot (regular box plot) plots one-variable data. The whiskers
on the plot extend from the minimum data point in the set
(
minX) to the first quartile (Q1) and from the third quartile (Q3)
to the maximum point (
maxX). The box is defined by Q1, Med
(median), and Q3 (page 12.29).
Box plots are plotted with respect to Xmin and Xmax, but ignore
Ymin and Ymax. When two box plots are plotted, the first one
plots at the top of the screen and the second plots in the middle.
When three are plotted, the first one plots at the top, the second
in the middle, and the third at the bottom.
NormProbPlot (normal probability plot) plots each observation
X in Data List versus the corresponding quantile z of the
standard normal distribution. If the plotted points lie close to a
straight line, then the plot indicates that the data are normal.
Enter a valid list name in the
Data List field. Select X or Y for
the
Data Axis setting.
• If you select
X, the TI-82 STATS plots the data on the x-axis
and the z-values on the y-axis.
• If you select
Y, the TI-82 STATS plots the data on the y-axis
and the z-values on the x-axis.
