What is the Sample Standard Deviation Calculator?

The Sample Standard Deviation Calculator is a statistical tool used to measure the spread or dispersion of a set of sample data. Unlike population standard deviation, this formula divides by n−1n-1n−1 instead of nnn to account for the fact that the data represents a sample rather than the entire population. By entering the sample values, the calculator computes the sample mean and sample standard deviation, which shows how much the individual data points deviate from the sample mean on average.

How to Use:

1. Enter Sample Values: Input all numeric values of the sample, separated by commas.
2. Click “Calculate”: The calculator outputs the sample mean and sample standard deviation.
3. Interpret Results: A smaller standard deviation indicates that the sample values are close to the mean, while a larger value indicates greater variability.
