Question

Quizplus · Accepted Answer

A deviation score is defined as the difference between an observation and the mean. Therefore, it is equal to the observation minus the mean, making B the correct choice. A is incorrect because standard deviation is a measure of variability, calculated as the square root of the variance. C is incorrect because range is the difference between the maximum and minimum values in a dataset. D is incorrect because mode is the value that occurs most frequently in a dataset. Finally, E is incorrect because quartile is any of three values that divide a dataset into four equal parts.
