CoolBrew is always found in the refrigerated section of the grocery store; most of the time it is near the milk or coffee creamers but some specialty stores place it near juice (breakfast items) or even ready to drink energy drinks (even though CoolBrew is a concentrate).
Best Answer: Standard deviation is a measure of how much the data is distributed around both sides of the mean. The wider the difference between the maximum and minimum values in a distribution, the bigger the standard deviation. In this case, the standard deviation is 32.3/73.9 or 43.7% of the mean. This is a large deviation, made even more significant by the fact that there is an absolute lower limit of zero.
Thus, the standard deviation is equal to the square root of (the average of the squares less the square of the average). See computational formula for the variance for a proof of this fact, and for an analogous result for the sample standard deviation.n the case where X takes random values from a finite data set, with each value having the same probability, the standard deviation is. or, using summation notation, The standard deviation of a (univariate) probability distribution is the same as that of a random variable having that distribution.
