Define Standard Deviation

Introduction for Learning Standard Deviation:
In this article let me help you on define standard deviation. If a student wants to learning standard deviation, he should have a clear idea about in arithmetic mean and deviation. In this, we are going to learning standard deviation with some example problems as shown below.

Definition for Standard Deviation:
A standard deviation is a statistical data of measure which can variability and spread. Standard deviation is a deviation of root mean square for the values in the arithmetic mean.

The following is the practice problems for learning define standard deviation.
Calculate the standard deviation for the given values 13, 33, 19, 28, 9 and 30.This could also help us on permutation and combination
Solution:
= 9.82
Calculate the standard deviation for the given values 38, 11, 8, 31 and 22.
Solution:
= 12.78
Calculate the standard deviation for the given values 29, 30, 20 and 17.
Solution:
= 6.48
