1.  The mean is the sum of the data divided by the number of pieces of data.  The median is the number in the middle when the data is arranged in order.  The mode is the number that appears the most in a set of data. Examples will vary. 2.  3, 6, 8, 9, 11, 21, 37  Mean =13.6 Median = 9 3.  9, 23, 25, 29, 31, 40, 46, 52, 64 Mean =  35.4 Median  =  31 4.  9, 12, 14, 16, 25, 46, 49, 58 Mean = 28.6 Median = 20.5 5.  3.7, 4.2, 5.7, 7.1, 9.0 Mean = 5.9 Median = 5.7 6.  85, 91, 101, 132, 151 Mean = 112 Median = 101 7.  0.2, 0.5, 0.6, 0.9, 1.7, 9.2 Mean = 2.2 Median = 0.75 (If you rounded to the nearest tenth, your answer would be 0.8) 8.  Answers will vary 9.  mode = 2
