Frequently Asked Questions
What is the difference between mean, median, and mode?+
Mean is the average (sum ÷ count). Median is the middle value when sorted. Mode is the most frequent value. For symmetric data they're similar, but for skewed data they can differ significantly.
When should I use median instead of mean?+
Use median when data has outliers or is skewed (like income data). Median is resistant to extreme values. For example, if most people earn $50K but one earns $10M, the median better represents the typical value.
Can there be multiple modes?+
Yes. If two values tie for most frequent, the data is bimodal. If all values appear equally often, there is no mode.
