Median Calculator
The Median Calculator helps you determine the middle value of a dataset quickly and accurately. It sorts your numbers automatically and calculates the median whether the dataset contains an odd or even number of values.
What Is the Median?
The median is one of the three primary measures of central tendency, along with the mean and mode. Unlike the mean, the median is not greatly affected by extremely high or low values, making it useful for skewed datasets.
Median Formula
For an odd number of values:
Median = Middle Value
For an even number of values:
Median = (Middle Value 1 + Middle Value 2) ÷ 2
How to Use the Calculator
- Enter numbers separated by commas.
- Click Calculate.
- The calculator sorts the numbers automatically.
- The median is displayed instantly.
Example 1 (Odd Number of Values)
Input: 3, 8, 12, 15, 20
Sorted: 3, 8, 12, 15, 20
Median = 12
Example 2 (Even Number of Values)
Input: 5, 10, 15, 20
Sorted: 5, 10, 15, 20
Median = (10 + 15) ÷ 2 = 12.5
Why Use the Median?
- Less affected by outliers.
- Ideal for skewed distributions.
- Easy to interpret.
- Commonly used in statistics and economics.
- Suitable for income, property prices, and survey data.

Frequently Asked Questions
What is the difference between mean and median?
The mean is the average of all numbers, while the median is the middle value after sorting.
When should I use the median?
Use the median when your data contains outliers or is not normally distributed.
Can the median be a decimal?
Yes. When there are an even number of values, the median is often the average of two middle numbers.
Conclusion
The Median Calculator provides a quick and reliable way to determine the middle value of any dataset. It is widely used in mathematics, statistics, finance, education, and scientific research.
