# Multiple data of the same value :
[ DATA ] < x value > [ x ] < Number of repeats >
(B) To input paired–variable / regression data using the following
syntaxes :
# Individual data-set : [ DATA ] < x value > [
# Multiple data of the same value :
[ DATA ] < x value > [ ] < y value > [ x ] < Number of repeats >
(Note) : Even you exit STAT mode, all data are still retained unless you
clear all data by selecting D-CL mode.

Displaying results

The values of the statistical variables depend on the data you input.
You can recall them by the key operations shown in the below table.
Single–variable statistics calculations
Variables Meaning
n ( [ n ] ) Number of the x values entered
x ( [2nd]+[ x ] ) Mean of the x values
Sx ( [2nd]+[ Sx ] ) Sample standard deviation of x values
σx ( [2nd]+[ σ x ] ) Population standard deviation of x values
∑x ( [2nd]+[ ∑ x ] ) Sum of all x values
2 2
∑x ( [2nd]+[ ∑ x ]) Sum of all x values
2
CP ( [2nd]+[ CP ] ) Potential capability precision of the x values
Minimum (CPU, CPL) of the x values, where
CPU is upper spec. limit of capability
CPK ( [CPK] ) precision and CPL is lower spec. limit of
capability precision
CPK = Min ( CPU , CPL ) = CP ( 1 – Ca )
Paired-variable statistics / Regression calculations
Variables Meaning
n ( [ n ] ) Number of x-y pairs entered
x ( [2nd]+[ x ] )
Mean of the x values or y values
y ( [2nd]+[ y ] )
