Median Calculator
Find the median of a dataset by identifying the middle value when observations are sorted.
Median (middle value)
9.0000
Median (middle value) vs Value 1 (smallest)
Formula
## How to Find the Median ### Steps 1. Sort all values from least to greatest 2. If n is odd, the median is the value at position (n+1)/2 3. If n is even, the median is the average of the two middle values The median splits the dataset so that half the values lie below it and half above it. Unlike the mean, the median is resistant to outliers.
Exemplo Resolvido
Find the median of the sorted values 3, 7, 9, 15, 22.
- 01Values already sorted: 3, 7, 9, 15, 22
- 02n = 5 (odd), so median position = (5+1)/2 = 3rd value
- 03Median = 9
Perguntas Frequentes
What if I have an even number of values?
Average the two middle values. For example, for 2, 4, 6, 8, the median is (4 + 6) / 2 = 5.
Why is the median preferred for skewed data?
The median is not pulled toward extreme values. For income data, which is typically right-skewed, the median gives a better sense of the typical household than the mean.
Is the median always one of the data values?
Only when n is odd. When n is even, the median is the average of two data points and may not appear in the dataset itself.
