Q: What is the median of the following numbers: 7, 9, 12, 15, 18, 20?
Solution:
Median = (12 + 15) / 2 = 27 / 2 = 13.5.
Steps: 6
Show Steps
Step 1: Write down the numbers in order: 7, 9, 12, 15, 18, 20.
Step 2: Count how many numbers there are. There are 6 numbers.
Step 3: Since there is an even number of values (6), the median will be the average of the two middle numbers.
Step 4: Identify the two middle numbers. The middle numbers are the 3rd and 4th numbers: 12 and 15.
Step 5: Add the two middle numbers together: 12 + 15 = 27.
Step 6: Divide the sum by 2 to find the average: 27 / 2 = 13.5.
