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

[Paragreen, Chris J]

I agree that measures are interrelated. I think if students can explain themselves as well as the IT teaching fraternity in relation to this, they must be at the upper end of the performance indicators. ☺

I shall ruminate on this over the weekend (while I assess my students’ responses to this very subject).

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- going out of date - the state of the real world has changed (a few new cows were put into the paddock) but the data has not been updated to reflect that change.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*.
