Answer:
18 is the median for this set of numbers.
Explanation:
If you lye(?) out the numbers in order:
3, 4, 18, 23, 29
You will see that 18 is right in the middle, making it the median. If there was a number next to 18 and the set of numbers were even you would have to find the mean of the two middle numbers.
For Example:
3, 4, 18, 20, 23, 29
To find the mean, you must add the two middle numbers and then devide it by two because that's the amount of numbers you added.
18+20=38
38/2=19
The medium would then be 19
