The median here is 29. Then you see how many number until the end of your data (in this case 4). If the number is odd then it will be the middle number in the second half of ur data. If the number is even than u take the 2 middle numbers in the second half of your data and find their averagein this case the third quartile would be [tex]\frac{37+43}{2}[/tex]which is 40.
