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

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
