CHAPTER 7
for US
The following is a list of statistical graph types available on the calculator.
Histogram
Broken line plot
Normal probability plot
Normal distribution plot
Box plot
Modified box plot
Scatter diagram
XYline
• For example, it is possible for PLOT 1
to be a Broken line plot using
+
as
plotting dots and PLOT 2 to be a Histgram.
<Example 5>
Here, we will take the data from example 1. A histogram will be made using the scores
for the math tests as PLOT 1. A broken line plot (plot:
) will be made using the physics
scores as PLOT 2. First, we will set a graph using the math scores (L1).
1. Press

.
2. Specify PLOT1 by pressing

Set whether to graph (on) or not (off)
Set whether 1-variable or 2-variable (set to
“XY” for 2-variable)
Set list to graph
Set frequency
Set graph format
• This screen shows that PLOT1 is off (graphing invalid) and is a 1-variable and that a
histogram of list 1 is selected. Press
®
to select “on”.
• In this screen, the highlighted location, as well as the displayed list name and graph
image diagram are selected.
• The cursor is positioned at the very top where “on” is displayed when first opening
the screen (flashing display).
* To clear the contents entered in “Freq”, move the cursor to the list name then press
