Editing Arithmetic mean (section)

==Symbols and encoding==
The arithmetic mean is often denoted by a bar ([[Vinculum (symbol)|vinculum]] or [[Macron (diacritic)|macron]]), as in <math>\bar{x}</math>.<ref name="JM"/>

Some software ([[Text processing|text processors]], [[web browser]]s) may not display the "x̄" symbol correctly. For example, the [[HTML]] symbol "x̄" combines two codes — the base letter "x" plus a code for the line above ( &#772; or ¯).<ref>{{Cite web|url=http://www.personal.psu.edu/ejp10/psu/gotunicode/statsym.html|title=Notes on Unicode for Stat Symbols|website=www.personal.psu.edu|access-date=2018-10-14|archive-date=31 March 2022|archive-url=https://web.archive.org/web/20220331114343/http://www.personal.psu.edu/ejp10/psu/gotunicode/statsym.html|url-status=dead}}</ref>

In some document formats (such as [[PDF]]), the symbol may be replaced by a "¢" ([[Euro coins|cent]]) symbol when copied to a text processor such as [[Microsoft Word]].
