Frequently Asked Questions
What is the difference between mean, median, and mode?
Mean = sum divided by count (the ‘average’). Median = the middle value when sorted. Mode = the most frequent value. For skewed data (like income), median is more representative than mean. Use all three for a complete picture.
When should I use median instead of mean?
Use median when data has extreme outliers. Average US income ($80k) looks very different from median income ($56k) because billionaires pull the mean up. Median house prices, salaries, and waiting times are more meaningful than means.
