8-8 Single-Variable Statistical Graphs
To draw single-variable statistical graphs, you must.use the SD Mode and the Statistical
graph
DRAW
Mode.
The
unit
lets
you
draw
bar
graphs,
line
graphs
and
normal
distribu-
tion curves using data you input.

Example “To draw a bar graph of the following data: \
Rank | Value | Frequency |
it 0° 1
2 10 3
3 20 2
4 30 2
5 40 3
6 50 5 1
7 60 6
8 70 8
9 80 15
i0.| 90 9 5
i 100 2
First, specify the range parameters. Since the maximum data value for x is 100, we will
set Xmax as 110, The maximum data value for y is 15, so set Ymax as 20.
~170— Init ire
Next, specify the number of bars by increasing the number of value memories..Since we
have
11
ranks,
we
should
increase
the
number
of
memories
by
11.
If
you
skip
this
step,
an error occurs when you try to-draw the graph.
