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.
Vice versa, variance is standard deviation squared. To calculate standard deviation from variance, only take the square root. In our example, the variance was 200, therefore standard deviation is 14.14. For calculating standard deviation of a data set, first calculate the variance and then find the square root.or sample variance and standard deviation, the only difference is in step 4, where we divide by the number of items less one. In our example we would divide 1,000 by 4 (5 less 1) and get the sample variance of 250. Sample standard deviation would be 15.81 (square root of 250).
