Add another 2 cents to the pile.I tend to agree with Robert that in
the context of data integrity 'correctness' and 'accuracy' are more or
less synonymous, but they each do have a different feel to them. "The
correctness of the data was called into question" versus "The accuracy
of the data was called into question" - maybe it's just me, but
'correctness' has a more holistic feel to it, while 'accuracy' feels
much more specific somehow. Hopefully students will never be asked to
pin down the subtle distinctionIn light of the discussion so far, I
can't resist this entry from a 1926 Webster's Dictionary in my
possession:"CORRECT, ACCURATE, EXACT, PRECISE, NICE agree in the idea
of conformity to standard, fact, or truth. CORRECT, the most colorless
term, denotes scarcely more than freedom from fault or error, as
judged by some (usually) conventional or acknowledged standard;
as, _correct_ dress, style, deportment; ... ACCURATE implies, more
positively, conformity to fact or truth attained by the exercise of
care; as, an _accurate_ investigation, statement, observer. ... EXACT
emphasizes the strictness or rigor of the agreement, which neither
exceeds nor falls short of the fact of standard; ... PRECISE stresses
rather sharpness of definition or delimitation, or scrupulous
exactness of conformity to the standard as often verges on excess; ...
NICE implies still greater, occasionally excessive, fineness or
delicacy of observation or discrimination ...

PS - It is woth noting that most writing on data integrity refers to
"accuracy and consistency" and does not mention "correctness"

Hi all, my 2c worth again - from the perspective of working with data
and on
database design since the early 90s.
We are talking here about data integrity.
We are not talking about the accuracy or precision of measurements in
terms
number of significant figures or decimal places.
We are not talking about data formats, eg dd/mm/yyyy versus
mm/dd/yyyy or
yyyy/mm/dd
Andrew's example of stating his height as 1.564334m IS a measurement
"accurate" to 6 decimal places but it is not accurate/correct as a
statement
of his height.
I still consider correctness and accuracy as being synonymous terms
when
talking about data integrity.

Hi all,
I have spoken about accuracy in terms of precision.
I could say I am about 1.8 metres tall. That is correct, but not
accurate.
I could say I am 1.564334 metres tall. That is accurate, but not
correct.
Each situation will require a different level of accuracy that is
acceptable
or expected.
Can't think of a situation where accuracy is important but
correctness not.

And I teach them that dates recorded in this format in a file-naming
convention is both correct and accurate as the files self-sort by
date.

Sorry I did mean the opposite! Big week.
Try again??.
I taught my kids that if you are asked for a date in DD/MM/YYY format
in a
program then whilst ?1st of September 2016? is accurate, writing
01/09/2016
is correct.

I'd say the opposite.
I don't think this question is ever going to be answered until we
have a
plebiscite, a Royal Commission or at least a dance-off competition.

I have read Mark's views on this
http://vceit.com/wp/correctness-versus-accuracy/
Don't think they helped :-)
I think they are essentially synonymous:
eg my phone number is 0477999111 is both accurate and correct.

Hi all,
As part of the five characteristics of data integrity we have both
accuracy
and correctness; how do we differentiate the two of these?
