listing steps to find the median
you want to teach a friend how to find the median when an even number of values is given. put the steps you need to teach your friend in the correct order.
cross off low/high pairs. put the numbers in order. divide the sum by 2. add the leftover numbers

Explanation:

Step1: Order the numbers

First, we need to arrange the given set of numbers in ascending (or descending) order. This is the foundational step to find the median for any data set. So the first step is "Put the numbers in order."

Step2: Cross off low/high pairs

After ordering the numbers, we start crossing off the smallest and largest numbers one pair at a time. Since the number of values is even, we will be left with two middle numbers after this process. So the second step is "Cross off low/high pairs."

Step3: Add the leftover numbers

Once we have the two middle numbers (after crossing off the pairs), we need to add these two numbers together. So the third step is "Add the leftover numbers."

Step4: Divide the sum by 2

Finally, to find the median (which is the average of the two middle numbers when the count is even), we divide the sum of the two leftover numbers by 2. So the fourth step is "Divide the sum by 2."

Answer:

1. Put the numbers in order.
2. Cross off low/high pairs.
3. Add the leftover numbers.
4. Divide the sum by 2.
