Answer:
add middle numbers and divide by two.
Explanation:
When you need to find the median with an odd set of numbers, you arrange the numbers in order from least to greatest and find the number in the middle of the set:
1 2 3
median is 2.
But, when you have an even set of numbers, you take the two middle numbers, add them together, then divide them by two (it's like finding the mean of those two middle numbers):
1 2 3 4
2 3
2+3=5
5÷2=2.5
median is 2.5
