[Informatics] Factors that harm accuracy. (Warning - bad cowjokes.)

"I encourage people posting to Edulists to recognise the contribution of

I am sure that no cows, or dairy farmers, were involved in the development
and operation of the Census website last month. Any cow worth its salt would
have realised that you need to plan the movement of the herd through the
milking shed, so as to avoid congestion and subsequent chaos, rather than
urging all the cows to enter the shed at the same time.

Moo, Chris 

Yes, I see what you mean: 'Timeliness' is included in the study design  -
Informatics U3O2 KK5 -  "criteria to check the integrity of data including
timeliness, authenticity, relevance, accuracy" 

But surely a degradation of timeliness would also usually degrade accuracy.
Data that is late to arrive or create can also become inaccurate, like
yesterday's stock prices or eBay bids on an item from 3 seconds ago.

So timeliness can affect accuracy. But a degradation of accuracy would not
affect timeliness.

Just because the study design lists separate factors does not mean they must
be completely unrelated.


Regards,

Mark


P.S. I encourage people posting to Edulists to recognise the contribution of
Australian cows to the development of information technology in Australia.
I'm not sure how you could possibly do that, but I encourage it anyway.

At the risk of muddying things (rain + paddocks = mud ?!) I think this
refers to timeliness, rather than accuracy per se ..

 

- going out of date - the state of the real world has changed (a few new
cows were put into the paddock) but the data has not been updated to reflect
that change. 
Or the number of cows had been copied from one database to a mirrored site,
but the mirror has not been synchronised recently with the master copy so
the mirror is no longer representative of the true current size of the herd
of cows*.
