[Yr11 Information Technology] yr11it Digest, Vol 129, Issue 3

Thu Dec 10 13:05:01 AEDT 2015

OK. I broke out the big guns and pulled out the mighty *Shorter Oxford
English Dictionary (volume 1)*.
It says (paraphrased):

*Accurate *

   - exact or correct
   - done with care

*Correct*

   - free from error
   - accurate

Gee. *Thanks*, SOED!

One interesting example I found online was this:

'Disciplining children is right, but physical punishment is not the correct
way.'

'Accurate' cannot be substituted for "correct" in that example.
It seems that while "correct" is a superlative (something is either
accurate or it's not), "accurate" is comparative, and allows a degree of
exactness or precision.

How that helps the key knowledge, I don't know.
Perhaps it means that "data should be not wrong [correct] and closely
resemble the actual value of the thing in the real world that they
represent [accurate]".

Regards
Mark
