Test Command List
k Z Test
1-Sample Z Test
Command: OneSampleZTest䡺
Description: Tests a hypothesis relative to a population mean when population standard
deviation is known. A 1-Sample Z Test is used for normal distribution.
Z =
o –
0
σ
µ
n
o : mean of sample data
µ 0 : assumed population mean
σ : population standard deviation
n : sample size
Command Syntax
Syntax 1 (list format)
“ µ condition”, µ 0 value, σ value, List, Freq (or 1)
* “Freq” can be omitted. Doing so sets “1” for “Freq”.
Syntax 2 (parameter format)
“ µ condition”, µ 0 value, σ value, o 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
σ : population standard deviation ( σ > 0)
List : data list
Freq : frequency (1 or list name)
o :mean of sample data
n : sample size (positive integer)
Input Example:
Syntax 1 (list format)
OneSampleZTest “≠”,0,1,list1,1
Syntax 2 (parameter format)
OneSampleZTest “≠”,0,1,11.82,1
Calculation Result Output
µ ≠ 0: test condition
z : z value
p : p-value
o:mean of sample data
x σ n–1: sample standard deviation (Displayed only for list format.)
n: sample size
