The median is the exact center of a distribution or data set. If you are looking for the median in a series with an odd number of numbers, it is very easy. The middle of a sequence with an even number of numbers is more difficult to find. Read on to easily learn how to find the median.

To step

Method 1 of 2: Method 1: Finding the median in a sequence with an odd number of numbers

  1. Organize your series of numbers from smallest to largest. If they are mixed up, put them right, starting with the smallest number and ending with the largest number.
  2. Find the number that is exactly in the middle. This means that there are exactly as many numbers before the number that is the median as after it. Count them to make sure.
    • There are two numbers before the 3, and two numbers after it. That means that 3 is the number that exactly in the middle.
  3. Ready. The median of a series with an odd number of numbers is always a number that is in the series itself. It is never a number that does not appear in the series.

Method 2 of 2: Method 2: Finding the median in a sequence with an even number of numbers

  1. Organize your series of numbers from smallest to largest. Use the same first step as in the previous method. An even number of numbers will have two numbers exactly in the middle.
  2. Calculate the average of the two numbers in the middle.2 and 3 both are in the middle, so you have to add 2 and 3 together and divide by 2. The formula for calculating the mean of two numbers is (the sum of the two numbers): 2.
  3. Ready. The median of a series with an odd number of numbers does not have to be a number that occurs in the series itself.
