Important: • All data currently input in the Stat Editor is deleted whenever

you exit the STAT Mode, switch between the single-variable and a paired-

variable statistical calculation type, or change the Stat Format setting on the

setup menu. • The following operations are not supported by the Stat Editor:

;, ;(M–), B(STO). Pol, Rec, and multi-statements also cannot

be input with the Stat Editor.

To change the data in a cell: In the Stat Editor, move the cursor to the cell

that contains the data you want to change, input the new data, and then

press .

To delete a line: In the Stat Editor, move the cursor to the line that you want

to delete and then press ).

To insert a line: In the Stat Editor, move the cursor to the location where

you want to insert the line and then perform the following key operation:

(STAT)(Edit)(Ins).

To delete all Stat Editor contents: In the Stat Editor, perform the following

key operation: (STAT)(Edit)(Del-A).

Obtaining Statistical Values from Input Data

To obtain statistical values, press  while in the Stat Editor and then

recall the statistical variable (S

x, 3x

, etc.) you want. 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.

an argument immediately before them. See “Calculating Estimated Values”

for more information.

To input the single-variable data x = {1, 2, 2, 3, 3, 3, 4, 4, 5}, using

the FREQ column to specify the number of repeats for each items

({x

; freq

} = {1;1, 2;2, 3;3, 4;2, 5;1}), and calculate the mean and

population standard deviation.
