To insert a constant at the cursor position ( See Example 52. ) :
1. Press [ CONST ] to display the physical constants menu.
2. Press
[ ] until the constant you want is underlined.
3. Press
[
].
Mode 1 - STAT
There are three menu operations in statistics menu :
1–VAR
( for
analyzing data in a single dataset),
2–VAR
( for analyzing paired
data from two datasets ) and
D–CL
( for clearing all datasets). See
Example 38.
Single-Variable / Two-Variable Statistics
Step :
1. From the statistics menu, choose
1–VAR
or
2–VAR
and
press [
].
2. Press [ DATA ] and there are three menus:
DATA–INPUT
,
LIMIT–SET
,
DISTR
. Please select
DATA–INPUT
and press
[
].
3. Enter an x - value and press [ ].
4. Enter the frequency (
FREQ
) of the x - value (in
1–VAR
mode) or the corresponding y - value ( in
2–VAR
mode )
and press [ ].
5. To enter more data, repeat from step 3.
6. Press [ 2nd ] [ STATVAR ] and scroll through the statistical
result menus by [ ] or [ ] to find out statistical variables
you want. ( See table below )
Variable
Meaning
n

Process capability
Step : ( See Example 53~54. )
1. Press [ DATA ] and there are three menus :
DATA–INPUT
,
LIMIT–SET
,
DISTR
. Please select
LIMIT–SET
and press
[
].
2. Enter an upper spec. limit value (
X USL
or
Y USL
), then
press [ ].
3. Enter a lower spec. limit value (
X LSL
or
Y LSL
), then
press [
].
4. Enter the datasets you want under
DATA–INPUT
mode.
5. Press [ 2nd ] [ STATVAR ] and scroll through the statistical
results menu by [ ] or [ ] to find out process capability
variables you want. ( See table below )
Variable
Meaning
Cax
or
Cay
Capability accuracy of the x values or y values
,
Cpx
or
Cpy
Potential capability precision of the x values or y
values,
,
Cpkx
or
Cpky
Minimum (C
PU
, C
PL
) of the x values or y values,
where C
PU
is upper spec. limit of capability
precision and C
PL
is lower spec. limit of
capability precision
C
pkx

(Note) : When calculating process capability in
2–VAR
mode, the
x
n
and y
n
are independent with each other.
Probability distribution
Step : ( See Example 55. )
1. Based on the datasets in
1–VAR
mode, press [ DATA ] and
there are three menu :
DATA–INPUT
,
LIMIT–SET
,
DISTR
.
Please choose
DISTR
and press [
].
2. Enter a
a
x
value, then press [
].
3. Press [ STATVAR ] and scroll through the statistical results
menu by [ ] or [ ] to find out probability distribution
variables you want. (See table below)

Variable
Meaning
t
Test
value
P ( t )
Represent the cumulative fraction of the
standard normal distribution that is less than the
value t
R ( t )
Represent the cumulative fraction of the
standard normal distribution that lies between
the value t and 0. R ( t ) =1 – ( t )
Q ( t )
Represent the cumulative fraction of the
standard normal distribution that is greater than
the value t Q ( t ) = | 0.5 – ( t ) |
Linear regression
Step : ( See Example 56. )
1. Based on the datasets in
2–VAR
mode, press [ STATVAR ]
and scroll through the statistical results menu by [ ] or [ ]
to find out
a
,
b
, or
r
.
2. To predict a value for x (or y) given a value for y (or x), select
the x ' (or y ' variable, press [
], enter the given value,
and press [
] again. (See table below)
