The range is completely determined by the two extreme score in a distribution. The standart deviation on the other hand, uses every score. a. compute the range ( choose either definition ), the variance, and the standard devian=tion for the following sample of n = 4 scores. Note that there are two scores located in the center of the distribution and two extreme values: Scores: 0, 6, 6, 12 B. Now we willincrease the variability by moving the two central scores out to the extremes. once again compute the range, the variance, and the standard deviantion. New scores: 0, 0, 12, 12 c. According to the range, how do the two distribution compare in variability? How do they compare according to the variance and standard deviation?
