Description: Tests a hypothesis relative to a population mean when population standard
deviation is unknown. A 1-Sample t Test is used for t distribution.

Command Syntax
Syntax 1 (list format)
“
µ condition”, µ
0
value, List, Freq (or 1)
* “Freq” can be omitted. Doing so sets “1” for “Freq”.
Syntax 2 (parameter format)
“
µ condition”, µ
0
value, o value, x σ
n –1
value, n value
Definition of Terms
µ condition : population mean value test conditions (“≠” specifies two-tail test,
“<” specifies lower one-tail test, “>” specifies upper one-tail test.)
µ
0
: assumed population mean
List : data list
Freq : frequency (1 or list name)
o : mean of sample data
x σ
n -1
: sample standard deviation ( x σ
n -1
> 0)
n : sample size (positive integer)
Input Example:
Syntax 1 (list format)
OneSampleTTest “
≠”,11.3,list1,1
Syntax 2 (parameter format)
OneSampleTTest “
≠”,11.3,11.52,0.62,5
Calculation Result Output
µ ≠ 11.3 : test condition
t : t value
p : p -value
o : mean of sample data
x σ
n –1
: sample standard deviation
n : sample size
