What do you mean by standard deviation ?

The term "standard deviation" refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed. In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean. For example: To determine the standard deviation, sum up all the numbers in the data set, divide by the total number of numbers, and the result is the standard deviation.
