The ages of six junior champion chess players are 16, 11, 8, 13, 7, and 11. Using the deviation-score method (i.e., the definitional formula used in class), find: a) the range of the ages. b) the variance of the ages. c) the standard deviation of the ages 5. Add the extreme score of 4 to the ages from #4 and recompute: a) The range of the ages. b) The variance of the ages. c) The standard deviation of the ages. d) Compare the ranges and standard deviations from #4 and #5. What generalization is illustrated by comparing these answers?
