A SCATTERPLOT is used to view a set of real data graphically. Consider the following data.
x  0  1  2  3  5 
y  3  4  8  9  10 
To create a scatterplot of this data, make sure that all the Y's are clear in
the menu.
Now select and set an appropriate Viewing Rectangle. Since the x values range from 0 to 5, choose a range slightly larger than that, namely 1 to 6. Since the y values range from 3 to 10, select 0 to 15.
Thus, theViewing Rectangle of [1, 6,1] by [0, 15, 1], has been selected. To set this Viewing Rectangle, press WINDOWand enter 1 for Xmin, 6 for Xmax, 1 for Xscl, 0 for Ymin, 15 for Ymax,and 1 for Yscl.
Now, press 2nd and then Y= [STAT PLOT]. The calculator screen should look the one on the left below. 1 is highlighted, so press ENTER to select the first plot. Now, select ON in the first row, then select the first TYPE. Xlist and Ylist should already be selected as and . The MARK selected does not matter, so choose one of them.

To enter the data for the scatterplot, press STAT, and select
1:Edit by pressing ENTER. If the lists
are not all cleared as shown in the screen below, go to see Clearing Lists.
Enter
the data values for X in and the data
values for Y in , keeping each pair together on the same horizontal
line. Then press GRAPH.
