do we say data is or data are?

Question

is it singular or plural

Answer 1

In Latin, data is the plural of datum and, historically and in specialized scientific fields, it is also treated as a plural in English, taking a plural verb, as in the 'data were collected and classified'.
In modern non-scientific use, however, despite the complaints of traditionalists, it is often not treated as a plural. Instead, it is treated as a mass noun, similar to a word like 'information', which cannot normally have a plural and which takes a singular verb. Sentences such as 'data was (as well as data were) collected over a number of years' are now widely accepted in standard English.

Answer 2

Data — ... is the plural of datum, meaning a piece of information
There are several words with Latin or Greek roots whose plural forms ending in A are constantly mistaken for singular ones. See, for instance, criteria and media. “Datum” is so rare now in English that people may assume “data” has no singular form. Many American usage communities, however, use “data” as a singular and some have even gone so far as to invent “datums” as a new plural. This is a case where you need to know the patterns of your context. An engineer or scientist used to writing “the data is” may well find that the editors of a journal or publishing house insist on changing this phrase to “the data are.” Usage is so evenly split in this case that there is no automatic way of determining which is right; but writers addressing an international audience of nonspecialists would probably be safer treating “data” as plural.

Answer 3

Technically, it is plural (singular is datum), but it is a collective noun and when used in a collective sense, the singular makes more sense: "The data on the flu vaccine shows it to be effective." Contrast: "The data from the experiment show a lot of scatter."

Answer 4

Technically, data is plural (datum is singular), but that's Latin.
