precision versus accuracy
Authored by: DannyB on Wednesday, May 29 2013 @ 05:31 PM EDT
My commute to work is 5 light years, 1,282,598,209 miles, 905 feet, 3 and 5/32
inches.

That is an extremely precise distance.

But the accuracy is off by over five light years.

From dictionary.com

The definition of accuracy:

1. the condition or quality of being true, correct, or exact; freedom from error or defect; precision or exactness; correctness.

The definition of precision:

2. accuracy; exactness: to arrive at an estimate with precision.
These two words sound synonymous to me.

accuracy in news is ... important
Sorry... I had to laugh at that because while that is correct - the main media appear to rely more on sensational journalism rather then accurate journalism :)

That all journalism SHOULD (nod to anonymous @ 6:38PM) be
accurate should go without saying.

I take PJ's point here to be that the law is a complex and
difficult topic, and so you not only need to be accurate (as
you always should be as a journalist) but also precise and
clear.

Precise because words have specific meanings(and not always
the common ones) and if you're casual with your words then
you'll end up delivering an inaccurate message. This lack of
precision is why we get mass hysteria from news headlines
like "LHC may create black holes" because they miss the fact
that they're REALLY REALLY small (and thus pop out of
existance almost immediately).

Clear because when words don't have the common meanings, you
have to make sure you're using both the right words AND
educating on what those words actually mean. In large part
this is why it's so hard to have a rational conversation
between a patent lawyer and a software engineer about
whether software is math.

All part of the Groklaw message. Education > all.

Note: these comments are my own, not PJ's. I'm sure she'll
correct me if she disagrees with what I say.

See here, a Stack Overflow answer detailing the difference.

precision versus accuracy

heh heh

you guys...

In law, precision is important, because there are so many footnotes to every thought you think you know, and so carefulness comes into the picture because you have to research to make sure you have it exactly right before you write something.

Accuracy is important, but it's not enough. Precision needs to be there too. I'll give you an example:

1. Aaron Swartz was facing 35 years if convicted of felonies under various computer statutes.

That is true. It's accurate. But it's not precise. He was in a worst possible case facing 35 years, but it was unlikely he'd actually get 35 years, because he was a first offender, the "victim" wasn't asking for long time or any time, plus he had fabulous lawyers and a lot of influential friends, and it's common for a prosecutor to state the ultimate penalty in a press release how many years could be asked for. It's also part of the negotiation process, trying to reach a plea deal.

Now, all that info is important, and without it, although you would be accurate to state that he faced 35 years, you wouldn't be precise in the way that you would be if you add all the rest.

Now, there is actually more to it. Laws overlap, I guess you could say, in the sense that sometimes you have to balance one type of law against another one, or one interest against another, contrasting one. Law is complicated for that reason, but for another: statutes don't always fit precisely the situation, without some wiggling. That wiggling is hard to pin down sometimes, and precision there means lawyers answering your question with "It depends." Lawyers look at more than one level. It's not like math.
