Answer:
Data Set 2, seventh graders:
Center: The median value is 54. (Count to the middle: it's the tenth value.) The set is bimodal, with modes at 53 and 55. (The mode is the number that occurs most frequently.)
Shape: The set looks to be fairly symmetrical, though data lies closer to the right than the left.
Spread: The range is 60-50 = 10, so it's less spread out than the sixth graders.
