Chapter 4.1: Scatter Plots

Lesson 4.1: Scatter Plots

Make a scatter graph to represent the following data:

1. Identify the values corresponding to the

horizontal axis and label axis2. Identify the values corresponding to

theVertical axis and label axis

3. Choose an appropriate scale for both axis

4. Graph each point

5. Choose an appropriate title for the graph

Make a scatter graph to represent the following data:

Hours (h) Pay in Dollars(d)1 4.502 9.003 13.505 22.508 36.00

Make a scatter graph to represent the SAME data on the graphing calculator:

1. Clear Calculator

2. – EDIT (Press so you can enter the ordered pairs into the calculator).

3. Enter all of the x-values in List 1. (Press after each one.)4. Enter all of the y-values in List 2. (Press after each one.)5.Check to be sure that all of the ordered pairs are correct.

Graphing calculator continues:

6.Go to STAT PLOT (Press ) #1 • Turn on Plot 1.• Select the type as disconnected dots.• Identify where to find the x-list and the y-

list. (L1, L2, etc. can be found as the 2nd function of the 1, 2, etc. keys.)

• Choose the mark.

Graphing calculator continues:

7. Press Set the window (based upon the ordered pairs you are using).

x-min = smallest x value on x-axisx-max = largest x value on x-axis

y-min = smallest y value on y-axisy-max = largest y values on x-axis
