Creating a Scatterplot Calculator Workshop
A scatter plot is a graph of data points. To graph the data, we must first
enter our data (x and y values) into the calculator. We enter these values
into lists. So, first we must become familiar with using lists.
To access the lists:
Press the stat button and choose #1, edit. You will
see the following screen.
The values that are in these two lists might vary from
the lists on your calculator.
To clear a list, use the arrow buttons to move the
cursor on L1 (or whichever list you want to clear)
and press clear enter. **DO NOT press delete when
on the name of the list. This will delete the list rather
that clear the column. If you do accidentally delete a
list, hit stat #5 enter.***
Entering data in a list:
Typically (but not always) L1 is used for x values and L2 is used for y values.

Once you clear L1 and L2, place the cursor in the L1 column and put in the
first x value, -4, and hit enter to insert the next x value. Continue this
procedure until all x values are entered. Then move the cursor to the L2
column and do the same to enter the y values.
When you are done entering the data you wish to plot, you should be able to
see all the values in the list.
