Creating a Dotplot
You can create a Dotplot by using the scatterplot option under STATPLOT. The steps to create
the dotplot are very similar to those needed to create the histogram. We will use the data stored
under the label WORK that we used to create the histogram in the previous example.
Press the STAT key.
Press the number 1 key.
Type in the numbers 1 through 50 in the L1 column.
Press the 2
nd
key and then the Y= key to get to STATPLOT.
Press the number 1 key.
Turn Plot1 On and highlight the scatterplot under Type.
Type L1 in for the Xlist:
Type WORK for the Ylist:
Select the period under Mark:
Press the Zoom Key.
Press the number 9 key to get to ZoomStat.
The Xlist values 1-50 are used only to spread out the data values. The distribution of the
numbers stored in the WORK list can be seen in the variability of the Ylist or on the vertical
axis.
