It is the middle value in the list of numbers. Can you find the median of these numbers?
What is the median of the following numbers?
Find the mean of the following: 1, 2, 1, 5, 5
Step 1: Sort the list → 1, 1, 2, 5, 5
Step 2: Count the number of numbers listed → 5
Step 3: There are five numbers listed, so the middle one will be the (5+1)/2 = 6/2 = 3rd number. Therefore, the median is 2.
Note: If an odd number of numbers are listed, pick the middle number. Otherwise, find the average of the middle two numbers.
