I can't see the diagrams but you will need to select the station with the largest inter-quartile range

here is an example... |dw:1358283291188:dw|

the upper quartile is Q3 and the lower is Q1, so the Inter Quartile Range is 

IQR = Q3 - Q1

in the example its  IQR = 25 - 10 

                                   = 15

hope this helps
