Quizplus · Accepted Answer

Standard deviation is a measure of the amount of dispersion or spread of a set of data values around the expected value or mean. It is calculated as the square root of the variance, which is the average of the squared differences from the mean. Therefore, choice B - "The dispersion around the expected value" - is the best answer.
