Obtaining Statistical Values from Input Data
To obtain statistical values, press
while in the Stat Editor and then
recall the statistical variable (

, etc.) you want. Supported statistical
variables and the keys you should press to recall them are shown below.

To input the single-variable data
x

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.
