The median of a set of numbers is the number that is in the very middle when all the numbers are in smallest to largest order.
To find the median of his weight we need to put the set of numbers into smallest to largest order:
48, 95, 101, 129, 132, 140, 143, 150, 157
Then find the number in the middle.
48, 95, 101, 129| 132 |140, 143, 150, 157
The median of the weight Jacob lifted recently is 132 pounds.
I hope this helped. :)
