Calculations with One Variable

The CALC menu calculates the following statistical values using one
SUM list.
Table 10-2. The CALC Menu for SUM Lists
Menu Key
 Calculates the sum of the numbers in the list.

Calculates the arithmetic mean (average).

Calculates the median.

Calculates the standard deviation.
 Calculates the difference between the largest and
smallest number.
 Finds the smallest (minimum) number in the list.
 Finds the largest (maximum) number in the list.
 Sorts the list in ascending order.
 Displays a series of menus for calculations with two
variables for curve fitting, estimation, weighted mean
and grouped standard deviation, and summation
statistics.

The calculator finds the sample standard deviation. The formula assumes
that the list of numbers is a sampling of a larger, complete set of data. If the
list is, in fact, the entire set of data, the true population standard deviation
can be computed by calculating the mean of the original list, placing that
value into the list, and then calculating the standard deviation.
Example: Mean, Median, and Standard Deviation. Suppose your
shop had the following phone bills during the past six months:
