The following shows the meaning of each item in the case of list data specifi cation.
Data ............................. data type
C-Level .........................confi dence level (0 < C-Level < 1)
σ
1 .................................population standard deviation of sample 1 (
σ
1 > 0)
σ
2 .................................population standard deviation of sample 2 (
σ
2 > 0)
List(1) ........................... list whose contents you want to use as data of sample 1
(List 1 to 26)
List(2) ........................... list whose contents you want to use as data of sample 2
(List 1 to 26)
Freq(1) ......................... frequency of sample 1 (1 or List 1 to 26)
Freq(2) ......................... frequency of sample 2 (1 or List 1 to 26)
Save Res .....................list for storage of calculation results (None or List 1 to 26)
Execute ........................executes a calculation
The following shows the meaning of parameter data specifi cation items that are different
from list data specifi cation.
̄ x 1 .................................mean of sample 1
n 1 ................................. size (positive integer) of sample 1
̄ x 2 ................................mean of sample 2
n 2 ................................. size (positive integer) of sample 2
After setting all the parameters, use c to move the highlighting to “Execute” and then press
the function key shown below to perform the calculation.
• 1 (CALC) ... Performs the calculation.
Calculation Result Output Example
Left ............................... confi dence interval lower limit (left edge)
Right ............................confi dence interval upper limit (right edge)
¯ x 1 .................................mean of sample 1
¯ x 2 .................................mean of sample 2
x 1
σ
n -1 ............................ standard deviation of sample 1
(Displayed only for Data: List setting.)
x 2
σ
n -1 ............................ standard deviation of sample 2
(Displayed only for Data: List setting.)
n 1 ................................. size of sample 1
n 2 ................................. size of sample 2
