Detailed explanation-1: -The correct option is the second one: B) The standard deviation is a measure of dispersion.
Detailed explanation-2: -Answer and Explanation: The given statement about standard deviation is absolutely true as standard deviation indeed measures of dispersion. The standard deviation can be calculated as a square root of the variance and it is also known as a method to measure how spread out are the values in a data set.
Detailed explanation-3: -What Is Standard Deviation?
