BOX-PLOTS ON YOUR TI-83


square


~follow the following procedure:

~The smallest data value (min), Q1, Med(Q2), Q3, & the largest data value (max) are known as the 5 number summary & are used to construct box-plots.

~Once your data set has been entered into a list, the TI-83 will 
construct a boxplot by pressing 2nd STAT plot (far top left), (1), enter, on (blinking), enter,  move curser to center bottom chart (regular type of boxplot), enter list where data is stored, enter Freq: 1,
Zoom 9 (sets up viewing window automatically). 

~If you choose the first type of boxplot in row 2 (modified), you will see any outliers as pts on your boxplot. Be careful, outliers close to each other may appear as one pt.

~Note: More than one boxplot may be shown if you use more that one plot & the data has been entered in different lists.

~This is a popular way of comparing two data sets.
