1. Find the arithmetic mean (average)
=> Sum of all values in the set, divided by the numbers of elements in the set
2. Find the sum of the squares of all values in the set
3. Divide output of (2) over the numbers of elements in the set
4. Substract the square of mean (1) from the output of (3)
5. Take the square root of the outcome of (4)
Example:
Set A={1,3,4,5,7}
1. (1+3+4+5+7)/5 = 4
2. (1*1+3*3+4*4+5*5+7*7)=1+9+16+25+49 = 100
3. 100 / 5 = 20
4. 20 - 4*4=20-16 = 4
5. SQRT(4) = 2
