Statistics A (Chapter 4: Measures of Central Tendency and Variability) 1). Explain why an extreme score or outlier (either a very high or a very low score) affects the mean more than it affects the mode and median. 2). What is the major problem with using the Range as the measure of variability? Consider the following four data sets A, B, and C for questions 3 and 4. A = {9, 10, 11,7,13} B = {10, 10, 10, 10, 10} C = {8, 9, 10, 11, 20} 3). Calculate the mode, median, and mean of each data set. Show all your work. Data Set A: mode: median: mean: Data Set B: mode: median: mean: Data Set C: mode: median: mean
