What is Standard Deviation?
Standard deviation measures the amount of variation or dispersion in a dataset. A low standard deviation indicates values are close to the mean, while high standard deviation indicates values are spread out. It is widely used in finance to measure volatility, in manufacturing for quality control, and in research to measure data reliability. Sample standard deviation (n-1) provides an unbiased estimate for population data.
How to use
Enter your dataset values separated by commas, spaces, or new lines. Select whether your data represents a sample (using n-1) or the entire population (using N). The calculator computes standard deviation, variance, mean, median, range, coefficient of variation, and other statistical measures.
