Median Calculator
Paste a list of numbers to find the median — the middle value when your data is sorted from lowest to highest. The median is often a better "typical value" than the mean when your data has outliers.

How It Works
First, all values are sorted from smallest to largest. If there's an odd number of values, the median is the single middle value. If there's an even number of values, the median is the average of the two middle values. For example, in [3, 1, 4, 1, 5] sorted to [1, 1, 3, 4, 5], the median is 3 (the middle of 5 values). In [1, 2, 3, 4], the median is (2 + 3) / 2 = 2.5.

Frequently Asked Questions
Why use the median instead of the mean?+
The median isn't pulled around by extreme values (outliers) the way the mean is. For example, if you're averaging incomes and one value is unusually high, the mean can be misleading while the median still reflects the "typical" value.
Do I need to sort my numbers before pasting them?+
No — paste them in any order. The calculator sorts your data automatically before finding the middle value.
What if my dataset has an even number of values?+
The median is the average of the two middle values once the data is sorted. For example, the median of [1, 2, 3, 4] is (2 + 3) / 2 = 2.5.
Can the median be used with the mode and standard deviation together?+
Yes — comparing the mean, median, and mode of the same dataset (and its standard deviation) gives a much fuller picture of your data than any single statistic alone, which is common in a final-year project's data analysis chapter.
