Frequently asked questions
How is the average (arithmetic mean) calculated?
Add up every value in the list, then divide by how many values there are. For 2, 4, 6: (2 + 4 + 6) ÷ 3 = 4.
Can I average negative and decimal numbers?
Yes. Enter them separated by commas, for example: -3.5, 2.25, 10. Negative values subtract from the sum exactly as they appear.
Average vs median — which one should I use?
The average uses every value, so a single extreme value (an outlier) can pull it far from most of the data. The median is the middle value and resists outliers. Salaries and house prices are classic cases where the median describes the data better.
