Scatter Plots on the Graphing Calculator

1. Setting Up Press the Y= key. Be sure there are no equations entered. If there are any equations, use the CLEAR key to delete them. 12/2/2018

2. Setting Up Be sure there are no equations entered below the 7th entry. Check that there are no equations entered below the visible screen. Use the down arrow and clear them. 12/2/2018

3. Clearing Lists To clear previous lists, press “second” +. Choose #4. Press ENTER. 12/2/2018

4. Clear Lists Press ENTER again. 12/2/2018

5. STAT Key The STAT Key is used to input statistical data. The STAT Key accesses lists similar to columns on a spreadsheet. Pressing “1:Edit” brings us to the lists. 12/2/2018

6. Edit Lists We are now ready to input the data. We have our blank lists. 12/2/2018

7. Input Lists Type the data into the lists. L1 = Width of rectangle L2 = Area of rectangle 12/2/2018

8. STAT PLOTS The STAT PLOT key allows us to choose one of three graphs to plot with the data in the lists. Choose Plot1 to start. 12/2/2018

9. Plot Menu Turn Plot1 ON Choose the type of graph (the first choice is a scatter plot). Choose the Xlist and Ylist. L1, L2 12/2/2018

ZOOM 9 ZOOM 9 sets the window to the data and plot the graph. 12/2/2018

10. The Graph All of the data is now plotted in the window. Reminder: Using the trace button reveals the coordinates of the points. 12/2/2018
