Definition of Terms
µ 1 condition : sample mean value test conditions (“≠” specifies two-tail test, “<”
specifies one-tail test where sample 1 is smaller than sample 2, “>”
specifies one-tail test where sample 1 is greater than sample 2.)
List(1) : list where sample 1 data is located
List(2) : list where sample 2 data is located
Freq(1) : frequency of sample 1 (1 or list name)
Freq(2) : frequency of sample 2 (1 or list name)
Pooled : On or Off
o1 : mean of sample 1 data
x1 σ n-1 : standard deviation of sample 1 (x1 σ n-1 > 0)
n1 : size of sample 1 (positive integer)
o2 : mean of sample 2 data
x2 σ n-1 : standard deviation of sample 2 (x2 σ n-1 > 0)
n2 : size of sample 2 (positive integer)
Input Example:
Syntax 1 (list format)
TwoSampleTTest “≠”,list1,list2,1,1,On
Syntax 2 (parameter format)
TwoSampleTTest “≠”,107.5,0.78,10,97.5,0.65,12,Off
Calculation Result Output
µ 1 ≠ µ 2 : test condition

df : degrees of freedom
o1 : mean of sample 1 data
o2 : mean of sample 2 data
x1 σ n–1 : standard deviation of sample 1
x2 σ n–1 : standard deviation of sample 2
xp σ n–1 : Pooled sample standard deviation (Displayed only when pooling is
turned on.)
n1 : size of sample 1
