Standard deviation - Wikipedia
https://en.wikipedia.org/wiki/Standard_deviation
Web ResultThe standard deviation of a random variable, sample, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation.

How to Calculate Standard Deviation (Guide) | Calculator
https://www.scribbr.com/statistics/standard-deviation/
Web ResultSep 17, 2020 · The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean. A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean.

Web ResultStep 1: Find the mean. Step 2: For each data point, find the square of its distance to the mean. Step 3: Sum the values from Step 2. Step 4: Divide by the number of data points. Step 5: Take the square root. An important note. The formula above is for finding the standard deviation of a population.

Web ResultStandard Deviation. The Standard Deviation is a measure of how spread out numbers are. Its symbol is σ (the greek letter sigma) The formula is easy: it is the square root of the Variance. So now you ask, "What is the Variance?" Variance. The Variance is defined as: The average of the squared differences from the Mean.

https://byjus.com/maths/standard-deviation/
Web ResultStandard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

https://statisticsbyjim.com/basics/standard-deviation/
Web ResultThe 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. Smaller values indicate that the data points cluster closer to the mean—the values in the dataset are relatively consistent.

Web ResultStandard 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.

Web ResultStandard deviation measures the spread of a data distribution. It measures the typical distance between each data point and the mean. The formula we use for standard deviation depends on whether the data is being considered a population of its own, or the data is a sample representing a larger population.
