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

,

1m

(M–),

1t

(STO). Pol, Rec, ÷R, 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

Y

.

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:

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

n

; freq

n

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

population standard deviation.
