Quizplus · Accepted Answer

The standard deviation is the square root of variance, which is a measure of how spread out a set of data is. It is calculated by taking the sum of the squared differences between each data point and the mean, dividing by the number of data points, and then taking the square root of the result. The other options, such as coefficient of determination, sum of squares, and range, are not directly related to the calculation of standard deviation.
