Kingsley, (01)
I generally agree. A proposition is a sentence. Technically, the
general notion of 'sentence' includes "modalities": declarative,
interrogative, imperative, hortative. So if your logic includes enough
modalities, every sentence is a proposition. I think you are talking
about "declarative sentences", when you refer to "statements". (02)
But making a sentence/proposition into a 'datum' requires one more
element -- the acceptance that the proposition is true. A 'datum' is a
proposition that is taken to be true. Interestingly, however, when one
deals with "outlier data" in a statistical analysis, one asks whether
there is some uncontrolled variable or the outliers are "dubious
observations", i.e., propositions that might not actually be true as
reported. (03)
I also agree, BTW, that a paragraph is just a small corpus -- a
collection of 1 or more sentences/propositions. And 'data' is a
collection of propositions that we take to be (simultaneously) true. (04)
BTW, we are not distinguishing here between the mental proposition (the
"meaning") and its expression, but that seems to be a big issue to other
contributors. That is, they see a 'sentence' as a particular form of
expression, which is, for example, distinct from a table of values. In
John's example, a telephone directory is not a collection of grammatical
sentences, but the meaning of each entry in the directory is a
proposition/datum. So we really have to be careful how we use these words. (05)
In my view, a table for which you don't know how to interpret a row is
not 'data'; it is just an image. It might as well be a JPEG of a
drawing. One might say that it is 'data' in the sense that the
interpretation is "In row 3, column B is 5", but then that is a sentence. (06)
