[Year 12 SofDev] Data Integrity: different between accuracyandcorrectness

Wed Sep 7 15:22:28 AEST 2016

OR

VCAA may confess to a error in the SD - however it happened - and admit that
they should never have included accuracy and correctness. 

Either "correctness" should simply be deleted or it should be replaced by
"consistency".

Now it is over to the VCAA because surely they must respond in some way, and
soon.

Please come in. Sit down.  
Don't step on the cat. 
And don't take any of my cows. I've counted them.

Let me take your hand. Yes. I can see by your palm that you are troubled.
A loved one has died? No?

Ah, now I see. 
You cannot tell the difference between accuracy and correctness.

There's a lot of that going around.

Let me consult my crystal ball... 
I see someone called 'VCAA'. Your spouse? No? It's a strange name. Is it
Italian?

Ah. Now it all becomes clear. I can see the future.

<spooky voice>

*	Prediction 1: VCAA is never going to explain the difference between
accuracy and correctness. Because they can't, in any sensible way.

*	Prediction 2: Instead, to avoid a sticky exam moment, VCAA will
never directly examine students on accuracy vs correctness*.

*	Prediction 3: The next study design will quietly edit out the
accuracy/correctness awkwardness.

</spooky voice>

Now, please cross my palm with silver before you leave the tent.

Madame Mark, the Mysterious.

* But I'd love to see them try.

It does not really matter we we all think (2c or otherwise), saying correct
and accurate are the same is not helpful.

The study design dot point on key knowledge ....
"characteristics of data that has integrity, including accuracy, timeliness,
reasonableness, authenticity, correctness"

So we need to advise our students about these five characteristics. 
Can we get some clarification from vcaa about this?
Potentially an Exam case study question could ask about different
characteristics of data. I hope not.

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 distinction
In 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 ...

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

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/ <http://vceit.com/wp/correctness-versus-accuracy/>
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?
