📊Mean
- ✓The sum of all values divided by the count
- ✓Uses every data point in its calculation
- ✓Works only with numerical data
- ✓Sensitive to extreme outliers
- ✓There is always exactly one mean
🔝Mode

- ✓Found by counting frequency, not calculating
- ✓Works with numbers and with categories
- ✓Unaffected by extreme outliers
- ✓A dataset can have one, several or no mode
Verdict
The mean balances all values into a single average; the mode simply names the most common value. Use the mean for numeric data and the mode when you need the most frequent category.
