C alculates the average for input data (sample data x).
C alculates the standard deviation of samples from input data (sample data x).
C alculates the standard deviation for a population from input data
(sample data x).
Displays the number of input data (sample data x).
C alculates the total for input data (sample data x).
C alculates the total to the second power for input data (sample data x).

A P P L IC AT IO N S :
Single-variable statistical calculations are used in a broad range of fields,
including engineering, business and economics. They are most often
applied to analysis in atmospheric obser vations and physics experiments,
as well as for quality control in factories.
N OT E :
1. Sample data refers to data selected randomly from the population.
2. Standard deviation of samples is determined by the sample data
shift from an average value.
3. Standard deviation for the population is standard deviation when
the sample data is deemed a population (full data).
