Standard Deviation Calculation

The standard deviation calculation is a very common measure of multiplication of a information set or distribution and extensively utilized in probability and statistics theory to asses the diversity or variability used. It describes simply how much variation or dispersion in the average mean, or predicted value. A minimal SD demonstrates the data points are generally close to the mean, while high SD demonstrates the data are distributed out over a wide variety of values
