Median Calculator

The Median Calculator calculates exact, real-time domain outputs in active voice. The Median Calculator sorts your raw dataset in ascending order and computes the 50th percentile Median (Q2), 25th percentile First Quartile (Q1), 75th percentile Third Quartile (Q3), Interquartile Range (IQR = Q3 − Q1), and Tukey outlier fences.

Median Calculator Mathematical Formula

\text{Median} = \begin{cases} x_{(n+1)/2} & \text{if } n \text{ is odd} \\ \frac{x_{n/2} + x_{n/2 + 1}}{2} & \text{if } n \text{ is even} \end{cases}

Median Calculator Worked Example

Dataset: 42, 15, 28, 19, 35, 23, 50 (n = 7).

  1. Sort ascending: 15, 19, 23, 28, 35, 42, 50.
  2. Middle element at position (7+1)/2 = 4th item -> Median (Q2) = 28.
  3. Q1 = 19, Q3 = 42, Interquartile Range (IQR) = 42 - 19 = 23.

Because the median depends only on the middle rank order, it is 100% immune to extreme outliers in income or home price data.

Median Calculator Frequently Asked Questions

Q: Why do economists report Median Household Income instead of Mean Income?

A small number of billionaire households pull the arithmetic mean upward, whereas the median accurately reflects the typical household right in the middle of the income distribution.
