ONE-VARIABLE DATA SET

Steps for creating a non-weighted data set's broken-line graph

1. Turn the calculator on and press						STAT	to enter the statistics menu.
Delete old data and enter the following data set for L1:
15	28	17	36	38	19		13	25	27	41

2.Check the data you have entered by pressing ▲ to move back through the data.

3.To graph a broken-line graph for the data set, first press 2ndF STAT PLOT ,

touch A PLOT1, and press ENTER . Turn PLOT1 on by pressing ENTER .

Press ▼ ENTER to choose one-variable data. Press ▼ 2ndF L1

ENTER to enter L1 as the data list. Clear the frequency prompt by pressing

DEL

ENTER

. Set the graph to a broken line graph by pressing

2ndF

STAT PLOT , touch B B.L., and double touch 3 Broken .

4.In our example, the smallest value is 13 and the largest value is 41.

The logical intervals for the data set would be 10-19 (tens), 20-29 (twenties), 30-39 (thirties), and 40-49 (forties). To set this viewing window, press WINDOW and set the horizontal axis to 10 < x < 50 with Xscl = 10.

Set the vertical axis to 0 < y < 5 with Yscl = 1.

5.To view the graph, press GRAPH .

6.

Press

TRACE

and then press

▼ repeatedly to trace the points making up

the broken-line graph.
