A good measure of dispersion should use all scores in a distribution to provide a comprehensive understanding of the variability present in the data. Additionally, it should describe the average or typical deviation of the scores to provide a representative measure of dispersion. Finally, it should be easy to calculate and interpret so that it is accessible to a wide audience of researchers and practitioners. Therefore, all three factors are important, and the best measure of dispersion would satisfy all three criteria, making choice D the correct answer.
