To find the median of a set of numbers, they must be in numerical order. The numbers provided by Noah are:
109, 115, 117, 127, 131, 136.
These numbers are already in order.
The median is calculated by finding the middle value of the ordered numbers. Since there are 6 numbers (an even count), the median will be the average of the two middle numbers:
The two middle numbers in this case are 117 and 127.
To find the median:
(117 + 127) / 2 = 244 / 2 = 122.
Noah did not make any error in ordering the numbers since they are already in order.
The correct response is:
**He did not make any error.**
