Expression 'We have very little data'

[Tamara]

Hi

I heard the expression(s) before - too little data, very little data (or, for example, very little commentary) - they are well-understood, but I supposed them to be very informal.

Today I heard 'very-little-data' in a very serious place and context, from a very serious person

Could you give some comment about 'We have very little data'?
Is it OK in/for standard English?

Hi Tamara,

'Data' has been accepted as a singular idea like 'information'.

Yes, Alan, I know.

But to me in this case 'little data' brings the idea of amount.
This is I can hardly accept 'little data' (not grammatically, but rather... semantically).

Got it! Yes, 'little' is used in the sense of 'not much' rather than small as in 'little people'

Just out of curiosity:
can I say, for example, 'very little detail is available'?
(implying 'not many')

And what happens if I add an article - a/the very little detail is available'?
