How to use this calculator

  • Enter your numbers.
  • Read the median.
  • Compare to mean to see how skewed the data is.

About this calculator

The median is the value in the middle of a sorted list — half the data is above, half below. For odd counts it's the literal middle. For even counts it's the mean of the two middle values. Median is the right "average" for skewed data because it's not pulled around by extreme values the way the arithmetic mean is.

Frequently asked

Why use median for income or house prices?+
Because a few extreme values (billionaires, mansions) pull the mean up dramatically. Median is closer to the "typical" experience.
How does median compare to mode?+
Median is the middle; mode is the most common value. They can differ — in [1, 2, 2, 3, 100], median = 2, mode = 2, mean = 21.6.
Is the median always one of the values in the list?+
For odd-count lists yes. For even-count lists, no — it's the average of two values, which may not be in the list.
How do quartiles relate?+
Q1 is the median of the lower half, Q3 of the upper half. The IQR (Q3 − Q1) is a robust spread measure.
Can the median be a decimal even with all-integer input?+
Yes — for an even count, the median is the mean of the two middle integers. [1, 2, 3, 4] → median = 2.5.
