Frequently asked questions
- What if there's a tie for the mode?
- The tool lists every value that ties for the highest frequency, so you might see two or three modes instead of one. If every number appears exactly once, it reports that there's no mode.
- How is the median calculated with an even set of numbers?
- It sorts your list and averages the two middle values. With an odd count, it just returns the single middle value after sorting.
- Does it matter how I separate my numbers?
- No. Commas, spaces, tabs, and line breaks all work, and you can mix them. The tool strips out anything that isn't a valid number before calculating.
