To mathematically

transform

the data in a list:

1. Put the data list onto the stack.

2. Perform the arithmetic necessary to transform each datum in the

list. For example, to perform the transformation,

x'

=

31n.c — 4,

press

f r ^ f L N 1

Calculating Single-Variable Statistics

21 If your statistical data measures a sample of a population, you

calculate sample statistics. If, however, your data measures the entire

population, you calculate population statistics.

The single-variable statistics built into the STAT application are:

MEflH

Returns the arithmetic mean of the data in the

selected column.

STD DEV

Returns the standard deviation of the data in the

selected column. It computes the version of the
standard deviation indicated by the TYPE s field

(sample or population).

vflRIflHCE

Returns the variance of the data in the selected

column. It computes the version of the variance

indicated by the TYPE" field (sample or population).

T

T

h

L

Returns the sum of the data in the selected column.

M

KIMIJM

Returns the value of the largest datum in the

selected column.

MINIflUfl

Returns the value of the smallest datum in the

selected column.
