Standard Deviation (Population)

Introduction to Standard Deviation Calculator

Standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. This formula represents the population standard deviation, which includes all members of a set.

Parameter usage:

• ...numbers = an array of numerical values

Output:

• standard_deviation = the standard deviation of the input numbers

Data validation

All inputs must be numerical values. If non-numerical values are entered or no values are provided, an error message will be displayed.

Practical Application

Standard deviation is commonly used in finance, weather forecasting, and sports analytics to assess the variability of data.
