TI-83 Plus Statistics 371
The prompt for outlier points is x= , except when the outlier is the
maximum point ( maxX ) or the minimum point ( minX ). When outliers exist,
the end of each whisker will display x= . When no outliers exist, minX and
maxX are the prompts for the end of each whisker. Q 1
, Med (median), and
Q 3
define the box.
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.
Ö (Boxplot)
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 ( Q 1
) and from the third quartile ( Q 3
) to the maximum point
( maxX ). The box is defined by Q 1
, Med (median), and Q 3
.
