  #2

mode stays the same = 9
average decreases, move value from right to left of "percieved" average
median =
(10 values)
iniatilly above 1, below 1.2
you move from right to left = median should decrease, between .9 and 1

  #3

mode most resistant to extreme values
mean changes the most with extreme values
median better predictor of central tendency in schewed distributions
