Is ‘data’ singular or plural?

In most writing data will be treated as a singular noun:

“This data shows how people use language” (rather than “these data show”).
“The data is clear and convincing” (rather than “these data are clear and convincing”).

In these examples data is a noncount noun, like information, meaning it refers to something that cannot be counted. It is treated like a singular noun even when if refers to multiple pieces of data (”Participants’ data is not kept after the survey ends”).
