📐 How It Works

Finds the middle value when data is sorted in order. For an even count of values, the median is the average of the two middle values. The median is resistant to outliers.

🔢 Worked Examples

• [3, 5, 7, 9, 11] → Median = 7
• [2, 4, 6, 8] → Median = (4+6)/2 = 5
• [1, 1, 1, 100] → Median = 1, Mean = 25.75

📋 Common Use Cases

• Median household income (avoids billionaire skew)
• Median house price in real estate
• Hospital wait time reporting
• Test score analysis where a few extreme scores exist

💡 Did You Know?

In the US, median income is always reported instead of mean income for household data — because a handful of ultra-wealthy households would otherwise inflate the average to an unrealistic level.

⚠️ Common Mistake

Forgetting to sort the data first — the median of [5, 1, 3] is 3 (sorted: 1, 3, 5), not 1 (the literal middle of the unsorted list).
