∙ 9y agoThe word accurate is a synonym for precise. So the most accurate (or precise) answer would be 57.213 because it is more accurate if the number is not rounded.
You could do it by saying that all your measurements were 10 centimetres - irrespective of what they actually were. That would be neither precise nor accurate but it sure would be consistent!
Yes, the markings on your 50 mL beaker would be accurate enough to use for precise meansurement of volumes. The markings on a 50 mL Erlenmeyer flask would also be accurate enough.
Millimetres would allow for more precision than decimetre. If you can measure a smaller quantity, this always allows you to be more precise and accurate.
Accuracy is how close to the truth and precision is how narrow the the range of uncertainty or error. For example in guessing weight, of 150 # person, an accurate guess could be 140 # +- 15 #. An inaccurate guess would be 145# +- 2#. The first guess is accurate but not precise, the second is inaccurate but more precise.
The word inaccurate means not accurate or imprecise. Some antonyms for the word inaccurate would be correct, right, factual, precise, true and accurate.
The adjective is "precise" (accurate). The noun is "precision." The astronomical term would be "precesses" (subject to precession). The similar plural words are "processes" (actions as part of an activity) and "princesses" (more than one princess).
Precisoin is how consistent you are to hitting a target, for instance if you were shooting free throws, and you always hit the front of the rim that would be precise but NOT accurate. And accuracy is both precision and accuracy. So instead of being precise by hitting the front of the rim, you would make the shot by being accurate.
A group of precise measurements are a group of repetitive measurements that are very close together. Ie the standard deviation between the measurements is small. Not to be confused with a accurate measurement! Think about it like this, if you measure a piece of wood 5 times and each time you get an identical answer then the measurement are said to be precise. If however if turns out that despite measuring the length 5 times and getting the same answer you discover that the length is significantly off from the "true" answer, then you were inaccurate!
Police speed guns in England are caliberated before they are used in speed tests on the road and when they complete their tests, how I don't know, but I would presume by testing it on their own vehicles?? I would say they are pretty much accurate.
Because important decisions are often made on the basis of measurements. Would you like your doctor to diagnose your illness on the basis of a very rough measure of you pulse / blood pressure / etc. Would you like your builder to build a house on approximate vertical angles? Or your car to be designed on rough calculations?
Because they defeat them
