The mean is 12,898,007.4, no mode, the median is 14,765,410, the midrange is 9,814,293.

Work Step by Step

The mean can be counted by summing all the data and dividing it by the number of data: $\frac{17,688,241+1+19,628,585+12,407,800+14,765,710}{5}=12,898,007.4$, the mean is 773.667. The mode is the data occuring the most times but here all data occurs one time, therefore there is no mode. The median is the average of the 1 or 2 (here 1) middle data: (14,765,410)/1=630.5, the median is 14,765,410. The midrange is the average of the highest and the lowest data: (19,628,585+1)/2=9,814,293, the midrange is 9,814,293. The one that differs very much from the others is the 1 dollar compensation, because it is much lower than the others.
