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).

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).

<Let’s check the results based on the previous data.>

69 (average value)

17.75686128 (standard deviation)

17.57839583 (standard deviation of the population)

50 (total count of data)
