The range is completely determined by the two extreme scores in a distribution. The standard deviation, on the other hand, uses every score.

a. Compute the range (choose either definition), the variance, and the standard deviation 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 will increase the variability by moving the two central scores out to the extremes. Once again, ccompute the range (choose either definition), the variance and the standard deviation for the4 following sample of n= 4 scores, Note that there are two scores located in the center of the distribution and tow extreme value. 0, 0, 12, 12

c. According to the range, how do the two distributions compare in variability? How do they compare according to the variance and standard deviation?
