The following shows the meaning of each item in the case of list data specifica-
tion.
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.
o
1
.................... sample 1 mean
x
1
σ
n -1
............... sample 1 standard deviation ( x
1
σ
n -1
> 0)
n
1
.................... sample 1 size (positive integer)
o
2
.................... sample 2 mean
x
2
σ
n -1
............... sample 2 standard deviation ( x
2
σ
n -1
> 0)
n
2
.................... sample 2 size (positive integer)
Example To perform a 2-Sample t Test when two lists of data are input
For this example, we will perform a µ

test for the data
List1 = {55, 54, 51, 55, 53, 53, 54, 53} and List2 = {55.5, 52.3,
51.8, 57.2, 56.5} when pooling is not in effect.
