The average relative distance of each point in the data set from the mean is known as what?

• A. Standard deviation
• B. Variance
• C. Mean deviation
• D. Coefficient of variation

Answer: (B)

The average relative distance of each point in the data set from the mean is known as mean deviation, which reflects how far each data point is from the mean on average. This concept highlights the dispersion of data points around the central tendency, making it a crucial measure in statistics for understanding variability. When calculating mean deviation, one takes the absolute values of the differences between each data point and the mean, then averages these values. While variance and standard deviation also measure dispersion, they do so in terms of squared differences and their square roots, respectively. The coefficient of variation, on the other hand, is a relative measure that indicates how much variation exists in relation to the mean but does not directly reflect average distances from the mean. Therefore, mean deviation is the most accurate term for describing the concept given in the question.
