Since spotting this in THR some weeks back, this has become my very most favoritest ever sig line.
Sent it to a professional editor friend, too.
Geez
What happened to reading Webster’s Dictionary
1 : freedom from mistake or error :
CORRECTNESSchecked the novel for historical accuracy
2 a: conformity to truth or to a standard or model :
EXACTNESSimpossible to determine with accuracy the number of casualties
b: degree of conformity of a measure to a standard or a true value— compare PRECISION entry 1 sense 2a
1 : the quality or state of being precise : EXACTNESS
2 a: the degree of refinement with which an operation is performed or a measurement stated
— compare ACCURACY sense 2b...
I like both of these. So the way I have always looked at it, posted earlier, is wrong.Precision is putting all your bullets in one hole.
Accuracy is having that hole where you want it.
I now return control of your web site to less mundane things
Yep. That happened to me in a muzzleloader 100 yard match. I shot a very nice group the size of a quarter. It was off, though, a tad to the right. The winner shot a larger but more centered group.Nice explanation. When I shoot 1,000 yard bench rest, I need precision and accuracy, but in 100 yard bench rest it depends on whether you are shooing Group or Score. You can have a great score with a mediocre group or a tight group with a poor score as the group is in the wrong place.

sounds like you are banging your head against a wall.when you measure the same part repeatedly with the same device.
precision has nothing to do with the amount of dispersion from the mean only that all members of the group are dispersed the same.If you get a tight group you’re looking at precision.
the group may still be precise if each shot is the same distance from the mean.fires four shots and gets them all within the the second smallest ring but none of them are close to each other
that would require a sight adjustment, or kentucky windage.that tight group is far from where you aimed
sight adjustmentThe new shooter probably thinks he’s looking at poor accuracy when in reality he is looking at
agreed, precision has no place here. the goal in shooting is, for each shot, to make poi (point of impact) minus poa (point of aim) the smallest distance you can make it. that is accuracy and that is all i am concerned about.ake accuracy every time.
You are going to have to explain that one.the group may still be precise if each shot is the same distance from the mean.
That is correct, and it contradicts what you said before.
which is NOT the same as the Google answer:precision has nothing to do with the amount of dispersion from the mean only that all members of the group are dispersed the same.
Neither Google nor Wikipedia are anything close to being authoritative, much less accurate. Both show you what dang near anyone has posted on the web, whether they know what they are taking about, or not.which is NOT the same as the Google answer
I like this approach.You can evaluate accuracy for a single shot.
To evaluate precision you must have multiple shots.
no, just so the spread is the same.there is very little spread about the mean value
you will have to explain that one.That is correct, and it contradicts what you said before.
Not worth the effort. Your understanding is not adequate.you will have to explain that one.
your post was not worth the effort either, but i'm trying to inform others.Not worth the effort. Your understanding is not adequate.
precision has nothing to do with the amount of dispersion from the mean only that all members of the group are dispersed the same.
both. maybe you will understand this concept with time. keep trying, kleanbore.Murf, you have said
And you have posted
"Precise measurements are ones in which there is very little spread about the mean value"
Which is it?
