Frequently Asked Questions
How do you calculate the average (mean)?
Add up all the numbers, then divide by how many there are. For 10, 20, 20, 30, 40 the sum is 120 and the count is 5, so the mean is 120 ÷ 5 = 24. This "arithmetic mean" is what people usually mean by "average".
What is the difference between mean, median, and mode?
The mean is the sum divided by the count. The median is the middle value when the numbers are sorted (or the average of the two middle values) — it is more robust to outliers. The mode is the value that appears most often. For 10, 20, 20, 30, 40 the mean is 24, the median is 20, and the mode is 20.
When should I use the median instead of the mean?
Use the median when your data has extreme values or is skewed — for example house prices or incomes, where a few very large values pull the mean upward. The median better represents a "typical" value in those cases, which is why it is often reported for salaries and property prices.
