Understanding Standard Deviation: A Comprehensive Overview

In Statistics, for many of the computational problems, we have to analyze the given data. Standard Deviation is a statistical method used to find or measure the amount of scatteredness around an average of data under observation. Dispersion means the difference between the original values and average values. The more this dispersion in the given data, the bigger the value of the standard deviation. Standard Deviation may be symbolized by sigma σ (a Greek letter) for the population S.D. Standard Deviation is the most commonly used measure of dispersion, which is based on all values given in data. It means
