•Always start data input with AB1(Scl) =to clear statistical memory.
•Input data using the key sequence shown below. <x-data>  P<y-data>  S
•The values produced by a regression calculation depend on the values input, and results can be recalled using the key operations shown in the table below.
| To recall this type of value: | Perform this key operation: | 
| Σx2 | AU1 | 
| Σx | AU2 | 
| n | AU3 | 
| Σy2 | AUr1 | 
| Σy | AUr2 | 
| Σxy | AUr3 | 
| o | AX1 | 
| xσn | AX2 |
