u 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 (
oo
oo
o
=
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.
u 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: ...
