Inputting Data

• In the SD Mode and REG Mode, the l key operates as the 7 key.

• Always start data input with !,(CLR)b(Scl)= to clear

statistical memory.

• Input data using the key sequence shown below.

SD Mode: <

x-data> 7

REG Mode: <

x-data> , <y-data> 7

• 77 inputs the same data twice.

• You can also input multiple entries of the same data using !,(;).

Data Input Precautions

• While inputting data or after inputting data is complete, you can use

the f and c keys to scroll through data you have input. If you

input multiple entries of the same data using !,(;) to specify the

data frequency (number of data items) as described above, scrolling

through data shows both the data item and a separate screen for the

data frequency (Freq).

• Input the new value and then press the = key to replace the old

value with the new one. This also means that if you want to perform

some other operation, you should always press the A key first to

exit data display.

• Pressing the 7 key instead of = after changing a value on the

display registers the value you input as a new data item, and leaves

the old value as it is.

• You can delete a data value displayed using f and c by pressing

!l(CL). Deleting a data value causes all values following it to

be shifted up.

• The message “Data Full” appears and you will not be able to input any

more data if there is no memory left for data storage. If this happens,

press the = key to display the screen shown below.

Press c to exit data input without registering

the value you just input.

Press b if you want to register the value you

just input. If you do this, however, you will not be able to display or

edit any of the data you have input.

• After inputting statistical data in the SD Mode or REG Mode, you will

be unable to display or edit individual data items any longer after

perform either the following operations: changing to another mode;

changing the regression type.

• Entering the REG Mode and selecting a regression type (Lin, Log,

Exp, Pwr, Inv, Quad) clear variables A through F, X, and Y.

• Do not use variables A through F, X, or Y to store data when

performing statistical calculations.

Obtaining Statistical Values from Input Data

Supported statistical variables and the keys you should press to recall

them are shown below. For single-variable statistical calculations, the

variables marked with an asterisk (*) are available.

Sum: Σ

*, Σx*, Σy

, Σy, Σxy, Σx

, Σx

y, Σx

, Number of Items: n*

, Σx, n .......... 11(S-SUM) 1 to 3

, Σy, Σxy....... 11(S-SUM)e 1 to 3
