2. An exercise about the median and the mean
    
   1. Find the median and the mean for the following sets of test scores:
       

      											Mean	Median
      Set 1	15	25	75	78	79	81	83	84	92	97
      Set 2	67	71	72	77	79	80	83	84	91	95

      
       
   2. The two sets of test scores have similar medians, but you probably found that there was a larger difference between the two means. Can you identify any particular data points that are making a significant contribution to this phenomenon?
