standard deviation calculator
Easily calculate the standard deviation of a series of numbers. Enter multiple values and instantly discover the spread of your dataset with this free standard deviation calculator.
The standard deviation is a statistical measure that shows how strongly values deviate from the mean . The larger the standard deviation, the greater the spread of the numbers in the dataset.
With this standard deviation calculator , you can easily calculate the spread of a series of numbers. Enter multiple values, separated by a comma or space, and the tool automatically calculates the standard deviation.
What is the standard deviation?
The standard deviation indicates how far values are from the mean on average. It is an important measure in statistics for measuring the dispersion of data .
A low standard deviation means that the values are close to the mean . A high standard deviation means that the values are widely spread out .
Example standard deviation
Dataset:
4, 5, 6, 7, 8
Average:
6
Because the numbers are close together, the standard deviation is relatively small.
Where is standard deviation used?
The standard deviation is used in, among others:
- statistics and data analysis
- science and research
- financial analysis
- quality control
- machine learning
