Obtaining Statistical Values from Input Data
You can use the operations in this section to recall statistical values
assigned to variables (σ
x
, Σx
2
, etc.) based on the data you input with the
Statistics Editor. You can also use the variables in calculations. The
operations in this section are performed on the statistical calculation screen
that appears when you press while the Statistics Editor is displayed.
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.
