The Standard Deviation calculator computes the population and sample standard deviation for a set of comma separated number values (x).
INSTRUCTIONS: Enter the following:
Standard Deviation (σ): The calculator returns both the sample and population standard deviation.
This standard deviation function is a prominent feature with other statistical functions in the(Stat Calc).
The term population implies that every possible entity was measured in the set of input data. However, it is not always possible to measure an entire population. That is when one uses a sample. For this reason, there are two standard deviations. Note that the sample standard deviation is always larger having a smaller denominator (n-1). This broadens the area around the mean included in one standard deviation.
Theare as follows:
