Key Takeaway:Understand which statistical measure best represents your dataset when dealing with outliers and skewed distributions.
Central Tendency Comparison
- **Mean**: The mathematical sum divided by count.
- **Median**: The exact middle number when values are ordered in ascending rank.
- **Mode**: The value appearing with the highest frequency.
Why Outliers Skew the Mean
In skewed data like household net worth or real estate prices, a handful of billionaires or mansions heavily inflates the mean. The median provides a more realistic representation of typical conditions.
Frequently Asked Questions
Can a dataset have multiple modes?
Yes. A dataset can be bimodal (two peaks) or multimodal if multiple numbers share the highest frequency.
