Check that all values use the same unit before calculating an average; a mixed list can produce a mathematically correct but misleading result.

Things to know before you start
The arithmetic mean can be misleading when a dataset contains extreme outliers; use a different statistic when appropriate.
Privacy and file handling
ToolVero is built around browser-based utilities where the individual tool supports local processing. When a tool loads a public JavaScript library, that library is used to perform the operation in the page. Do not enter passwords, private keys or other highly sensitive information into any tool unless you understand the processing involved.
