| Confidence Interval (INTR) |
The following shows the meaning of each item in the case of list data specification. | |
Data ............................ | data type |
confidence level (0 | |
σ1 ................................. | population standard deviation of sample 1 (σ1 > 0) |
σ2 ................................. | population standard deviation of sample 2 (σ2 > 0) |
List(1) .......................... | list whose contents you want to use as data of sample 1 |
| (List 1 to 20) |
List(2) .......................... | list whose contents you want to use as data of sample 2 |
| (List 1 to 20) |
Freq(1) ........................ | frequency of sample 1 (1 or List 1 to 20) |
Freq(2) ........................ | frequency of sample 2 (1 or List 1 to 20) |
Save Res ..................... | list for storage of calculation results (None or List 1 to 20) |
Execute ....................... | executes a calculation |
The following shows the meaning of parameter data specification items that are different from list data specification.
o1 ................................. | mean of sample 1 |
n1 ................................. | size (positive integer) of sample 1 |
o2 ................................. | mean of sample 2 |
n2 ................................. | size (positive integer) of sample 2 |
After setting all the parameters, align the cursor with [Execute] and then press the function key shown below to perform the calculation.
• 1(CALC) ... Performs the calculation. Calculation Result Output Example
Left .............................. | interval lower limit (left edge) |
Right ............................ | interval upper limit (right edge) |
o1 ................................. | mean of sample 1 |
o2 ................................. | mean of sample 2 |
