B)measures of variability
C)the result of subtracting each score from the median
D)the average of the mean and the standard deviation

Question

Quizplus · Accepted Answer

Measures of variability, such as range, variance, and standard deviation, determine how spread out scores are from each other. Measures of central tendency, such as mean, median, and mode, only describe the center of the distribution and not the extent of the differences between scores. Subtracting each score from the median may indicate the deviation from the central point but does not provide a comprehensive measure of variability. The average of the mean and standard deviation is not a commonly used mathematical calculation in statistics.
