Standard Deviation The Standard Deviation is a measure of how spread out numbers are from the normal. The symbol for Standard Deviation is sigma (sigma), which has the following formula: sigma = squareroot 1/N sigma_i = 1^N (x_i - mu)^2 To calculate the standard deviation of those numbers: Work out the Mean mu (the simple average of the numbers) Then for each number: subtract the Mean and square the result Then work out the mean of those squared differences. Take the squareroot of that and we are done! Example: A 20 students took a C++ quiz in which they scored the following grades: 9, 2, 5, 4, 12, 7, 8, 11, 9, 3, 7, 4, 12, 5, 4, 10, 9, 6, 9, and 4.
