data

In modern English, "data" is most commonly used as an uncountable noun (like "water" or "information"). This means people usually say "the data is" rather than "the data are." However, in very formal scientific writing or academic papers, some people still treat it as the plural form of "datum." In these specific cases, you might see it used with a plural verb (e.g., "the data suggest"). When talking about computers and mobile phones, "data" almost always refers to the amount of internet usage allowed by a service provider.
