Symbol . σ (mathematics, statistics) Standard deviation. (mathematics) Sum of divisors. (mathematics) Braid group algebra. (physics, scattering) Cross section. (linguistics, phonology) Syllable. (spatial databases) The select operation. The Stefan-Boltzmann constant. A shielding constant.

Standard deviation, denoted by the symbol σ, describes the square root of the mean of the squares of all the values of a series derived from the arithmetic mean which is also called the root-mean-square deviation. 0 is the smallest value of standard deviation since it cannot be negative. When the elements in a series are more isolated from the mean, then the standard deviation is also large.

Basically, a small standard deviation means that the values in a statistical data set are close to the mean of the data set, on average, and a large standard deviation means that the values in the data set are farther away from the mean, on average. The second data set isn't better, it's just less variable.
