Answer:
Median
Step-by-step explanation:
I know that you can't do Range, since it's skewed right.
The mean can't be it since it's also not representative when it's skewed right.
I'd say Median, or IQR at first glance but if you look at a graph, the IQR might follow with the skewed and move over a bit. 
That leaves Median.
