Inputting Statistical Data
If you select the SD Mode or REG Mode before specifying a program
number (P1 through P4), you can input statistical data as part of your
program.
• Input statistical data using the
S
key, just as you normally do (page 25).
• In addition to values, you can also input calculation expressions as data.
• Example 1:
To determine
o
of the following data
(
ooooo
=
30.875
)
(SD Mode) Scl: 30; 2 DT: 27 DT: 32; 5 DT:
o
*
* You do not need to specify the frequency when inputting a data item that
has a single occurrence.
• Example 2:
To determine regression coefficients A, B, and C for the
following data
(
A = 3, B = –2, C = 1
)
(REG (Quad) Mode) Scl: 3,6; 2 DT: 4,11 DT: 6,27; 2 DT:
A
^
B
^
C

**A, B, and C are not variable names. They are regression coefficients.

Memory Calculations
You can perform memory calculations in a program by inserting
M
+ and
M
–.
• Example:
... : 2
×
3 M+ : ...
u
Percent Calculations
You can perform percent calculations in a program by inserting
%
.
• Example:
... : 250 + 280 % : ...
Note that you cannot perform percent calculations like the following in a
program:
a
×
b
%+,
a
×
b
%–.
u
Rnd
You can round a value by using
Rnd
in a program.
• Example:
1
÷
3 : Rnd: ...
