    How do you find the standard deviation?

    Question #79439. Asked by FunTrivia17. (Apr 25 07 12:29 AM)

    		In probability and statistics, the standard deviation of a probability distribution, random variable, or population or multiset of values is a measure of the spread of its values. It is usually denoted with the letter σ (lower case sigma). It is defined as the square root of the variance. In other words, the standard deviation is the root mean square (RMS) deviation of values from their arithmetic mean. (Wikipedia)
