1) 
   The rest of the class changed their answer to mean because there was no outlying number  
   that would make the answer median.
2)
   2.50, 2.50, 5.00, 5.00, 10.00, 10.00, 10.00, 10.00, 15.00, 17.00, 20.00
  
  mode= 10.00   median= 10.00   mean= 9.7272
I would choose the mean because there is no outlying number to make the answer median and for the mode there is 4 numbers on one side and 3 on the other. The mean is also more central in the number values.

  1. Justin,

    Your calculations are right and I agree mean would be a much better measure of average. Remember to show your process of how you got the median of 10 or mean of 9.7. It is incomplete and does not fully show your understanding.
