Standard deviation - Wikipedia
WEBStandard deviation may be abbreviated SD, and is most commonly represented in mathematical texts and equations by the lowercase Greek letter σ (sigma), for the population standard deviation, or the Latin letter s, for the sample standard deviation.
How to Calculate Standard Deviation (Guide) | Calculator
WEB17. Sept. 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.
Calculating standard deviation step by step - Khan Academy
WEBOverview of how to calculate standard deviation. The formula for standard deviation (SD) is. SD = ∑ | x − μ | 2 N. where ∑ means "sum of", x is a value in the data set, μ is the mean of the data set, and N is the number of data points in the population.
Standard Deviation: Interpretations and Calculations
WEBThe 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.

Standard deviation - Math.net
WEBStandard 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.
Standard Deviation and Variance - Math is Fun
WEBThe 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.
