7-9-8 Tests

Definition of Terms

∝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

x1σn-1 :

standard deviation of sample 1 (x1σn-1> 0)

n1 :

size of sample 1 (positive integer)

o2 :

mean of sample 2 data

x2σn-1 :

standard deviation of sample 2 (x2σn-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
