- 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 )
- Standard Deviation - GeeksforGeeks
Standard deviation is a measure used in statistics to understand how the data points in a set are spread out from the mean value It indicates the extent of the data's variation and shows how far individual data points deviate from the average
- 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

It tells how the values are spread across the data sample and it is the measure of the variation of the data points from the mean The standard deviation of a data set, sample, statistical population, random variable, or probability distribution is the square root of its variance
- Standard Deviation and Variance - Math is Fun
Deviation just means how far from the normal The Standard Deviation is a measure of how spreadout numbers are
- Standard Deviation: Interpretations and Calculations - Statistics by Jim
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
