Data ................ data type
µ
1
.................... sample mean value test conditions (“
G
µ
2
” specifies two-tail
test, “<
µ
2
” specifies one-tail test where sample 1 is smaller
than sample 2, “>
µ
2
” specifies one-tail test where sample 1 is
greater than sample 2.)
List1 ................ list whose contents you want to use as sample 1 data
List2 ................ list whose contents you want to use as sample 2 data
Freq1 .............. frequency of sample 1
Freq2 .............. frequency of sample 2
Pooled ............ pooling On or Off
Execute .......... executes a calculation or draws a graph
The following shows the meaning of parameter data specification items that are
different from list data specification.

............... sample 1 standard deviation (

1
σ
n -1
> 0)
n

.................... sample 1 size (positive integer)
o
2
.................... sample 2 mean
x

σ
n
-1
> 0)
