Standard Deviation Calculator
A standard deviation calculator is a statistical tool used to measure the amount of variation or dispersion in a set of values. It provides insights into how spread out the numbers are from their average (mean) value. This calculator is essential for researchers, analysts, and students working with data in various fields, including science, finance, and social studies.

FAQ
What's the difference between population and sample standard deviation?
Population standard deviation is used when you have data for an entire population. Sample standard deviation is used when you only have a subset of the population and want to estimate the standard deviation for the entire population.
How accurate is this calculator?
Our calculator uses precise mathematical formulas and can handle up to 15 decimal places, ensuring high accuracy for most practical applications.
Can I use this calculator for my homework?
Yes, you can use this calculator to check your work. However, we recommend learning how to calculate standard deviation manually as well, as it's an important skill in statistics.
Is there a limit to how many numbers I can input?
Our calculator can handle up to 1000 data points. For larger data sets, we recommend using specialized statistical software.
