What is Standard Deviation of the Frequency Table

The standard deviation is the square root of the arithmetic mean of the sum of squares of the deviations from the mean. Strictly and mathematically, but absolutely incomprehensible. This is a verbal description of the formula for calculating the standard deviation, but to understand the meaning of this statistical term, let's deal with everything in order.

Imagine a shooting range, target and arrow. The sniper shoots at a standard target, where hitting the center gives 10 points, depending on the distance from the center, the number of points decreases, and hitting the outer areas gives only 1 point. Each shooter's shot is a random integer value between 1 and 10. A bullet-riddled target is a great illustration of the distribution of a random variable.
