The following shows the meaning of each item in the case of list data specification.
Data ................ data type
µ ..................... population mean value test conditions (“G µ
0
” specifies two-
tail test, “< µ
0
” specifies lower one-tail test, “> µ
0
” specifies
upper one-tail test.)
µ
0
.................... assumed population mean
List .................. list whose contents you want to use as data
Freq ................ frequency
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 ..................... sample mean
x σ
n -1
................ sample standard deviation ( x σ
n -1
> 0)
n ..................... sample size (positive integer)
Example To perform a 1-Sample t Test for one list of data
For this example, we will perform a µ G
G G G G
µ

test for the data
List1 = {11.2, 10.9, 12.5, 11.3, 11.7}, when µ
0
= 11.3.

µ G 11.3 .......... assumed population mean and direction of test
t ...................... t value
p ..................... p-value
o ..................... sample mean
x σ
n -1
................ sample standard deviation
n ..................... sample size
The following key operations can be used to draw a graph.
