Médiane

How to use it

1. Dataset: 23, 17, 31, 25, 19, 28, 22 (n=7)
2. Sort ascending: 17, 19, 22, 23, 25, 28, 31
3. Find middle position: (7+1)÷2 = 4th value
4. Median = 23

Common mistakes

• ⚠️ Not sorting the data before finding median
• ⚠️ Using mean instead of median for skewed distributions
• ⚠️ Incorrectly averaging middle two for even-sized datasets

Worked example

Find the median of the dataset: 23, 17, 31, 25, 19, 28, 22.

The median {median} is the middle value when data is sorted: {sorted}.
