Show answer & explanation
Correct answer: C
Measures of dispersion quantify data variability. Range, quartile deviation, and standard deviation are valid metrics for spread. However, the sum of deviations about the mean is always zero, making it unsuitable as a dispersion measure. Therefore, items A, B, and D constitute the correct set of measures.
