Standard Deviation Calculator
- Standard deviation is a measure of the amount of variation or dispersion of a set of values around their mean.
- A low standard deviation indicates that the values are clustered closely around the mean, while a high standard deviation indicates that the values are more spread out.
- The formula for standard deviation is the square root of the variance, which is the average of the squared differences of each value from the mean.
- Standard deviation is commonly used in statistics to describe the spread of a data set and to compare the variability of different data sets.
