Median Formula

The median is the middle value in a sorted dataset. If there is an even number of values, the median is the average of the two middle values.

Formula:
For odd number of values: Middle value
For even number of values: Average of two middle values
Steps

How to Calculate Median

To calculate the median, follow these steps:

  1. 1
    Sort all numbers in ascending order
  2. 2
    If the number of values is odd, the median is the middle value
  3. 3
    If the number of values is even, the median is the average of the two middle values

For example, to find the median of 2, 4, 6, 8, 10:

Example Calculation:
Sorted numbers: 2, 4, 6, 8, 10
Number of values: 5 (odd)
Median = 6 (middle value)
Examples

Median - Practical Examples

Example 1 Test Scores

A student's test scores are: 85, 90, 88, 92, 87. What is the median score?

Sorted scores: 85, 87, 88, 90, 92
Number of scores: 5 (odd)
Median = 88 (middle value)

Example 2 Daily Temperatures

The daily temperatures for a week are: 72°F, 75°F, 70°F, 68°F, 73°F, 71°F, 74°F. What is the median temperature?

Sorted temperatures: 68, 70, 71, 72, 73, 74, 75
Number of temperatures: 7 (odd)
Median = 72°F (middle value)

Example 3 Monthly Expenses

Monthly expenses for a year: $1200, $1300, $1250, $1400, $1350, $1300, $1250, $1200, $1300, $1350, $1400, $1300. What is the median monthly expense?

Sorted expenses: 1200, 1200, 1250, 1250, 1300, 1300, 1300, 1300, 1350, 1350, 1400, 1400
Number of expenses: 12 (even)
Median = (1300 + 1300) / 2 = $1300
