well the nice thing about the data set is that it is already arranged in ascending order... 

so the Minimum = smallest value in the set
          Maximum = largest value in the set

next you need to find the physical middle of the data... called the median... 
just cross the numbers off from either end and work into the middle. 

lower quartile or Q1 is the middle of the bottom half of the data... median to minimum

the upper quartile is the middle of the upper half  Median tomaximum value

hope it helps
