Step 1:  Know about the outlier.

              NOTE: An outlier is an extreme value in a data set that is either much

               larger or much smaller than all the other values.

             GIVEN:  200, 340, 145, 559, 702, 290, 348, 256, 1200


Step 2: Identify the outlier        

             look for the value that is either much larger or much smaller than all the

             other values. The value 1200 is an outlier because it is much larger than all

             other values.

                  Outlier is "1200"
