[Year 12 SofDev] Data Integrity: different between accuracy andcorrectness

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?
Thanks
