The following shows the meaning of each item in the case of list data specification.
Data ............................ data type
C-Level ........................ confidence 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 specification items that are different
from list data specification.
o
1
................................. mean of sample 1
n
1
................................. size (positive integer) of sample 1
o
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 .............................. confidence interval lower limit (left edge)
