What is the difference between mean, median, and mode?

Coding Now Expert • Jun 13, 2026 • 82 views

**Mean** — sum divided by count. Sensitive to outliers.
**Median** — middle value when sorted. Robust to outliers.
**Mode** — most frequent value.

Example: [1, 2, 2, 3, 100]
- Mean = 21.6 (skewed by 100)
- Median = 2 (more representative)
- Mode = 2

Use median when data has outliers (e.g., salaries, house prices).
