- Standard deviation - Wikipedia
The standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance (For a finite population, variance is the average of the squared deviations from the mean )

Deviation just means how far from the normal The Standard Deviation is a measure of how spreadout numbers are
- Standard Deviation - Definition, Symbol, Formula, Graph, Examples
Standard deviation is a statistical measure that shows how much a group of data is spread out or dispersed from its mean value (average) A smaller standard deviation value indicates that the values are close to the mean, whereas a larger value means the dataset is spread out further from the mean

The standard deviation is the average amount of variability in your dataset It tells you, on average, how far each score lies from the mean
- Standard Deviation Formula and Uses, vs. Variance - Investopedia
Standard deviation is a statistical measurement that looks at how far discrete points in a dataset are dispersed from the mean of that set It is calculated as the square root of the variance

The standard deviation (SD) is a single number that summarizes the variability in a dataset It represents the typical distance between each data point and the mean
- Standard deviation - Math. net
Standard deviation is a statistical measure of variability that indicates the average amount that a set of numbers deviates from their mean The higher the standard deviation, the more spread out the values, while a lower standard deviation indicates that the values tend to be close to the mean
