Precision is a measure of how close to each other repeated measurements are. Accuracy is how close to a target value the measurement is. The only reason this unneccessary bit of info is in your book is to cram kids' heads with useless info. Very few scientists or engineers care about this trivia. Real science is about understanding how things work.

precisions means that your results are repeated over and over again with very similar results.
Accuracy is the goal for the measurement-what you hope to obtain.
So if you are trying for a distance of 1cm, and get repeated results as 1.6 cm, that is good precision and poor accuracy.

∙ 15y agoPrecision has to do with the ability of your measuring instrument. For example, a ruler may be able to measure down to maybe 1 mm. A caliper, on the other hand, is a much more precise measuring instrument and may be able to measure to hundreds or thousandths of a millimeter.
Accuracy has to do with how close your measurement is to the actual value. For example, you may measure the diameter of a penny with a caliper (a very precise instrument) and report your result as 2.1023 mm (an obviously incorrect - but very precise - value) because you don't know how to read the caliper. In other words, your measurement of the penny is precise but not accurate.

∙ 12y agoYes. In fact, almost all measurements are approximations. Even the most accurate of scientific devices have a degree of uncertainty to them.

Which measurement is more precise 57 57.2 57.21 or 57.213?
The 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.
How can a series of measurements be precise without being accurate?
Precision is the number of significant figures, a function of the instrument / procedure used. Accuracy describes measurement error, indicating how closely that the measurement represents the actual value. Errors affect accuracy... like the butcher's thumb on the scale.
Can a flask perform accurate measurements?
It depends on what flask and what the quality of it is. If there is a hole in the flask, then obviously, no measurements. Most of the time, flasks do NOT give the most accurate measurements. Although, they do give more accurate measurements than a human eyeball and flasks do have their strengths compared to other tools as well.
What is the precise measurements 24 quarts or 49 pints?
49 pints
Systematic error produces results that are precise but not?
accurate
Can a measurements be both precise and accurate?
yes...
What provides a more accurate description of matter than measurements?
There is no more accurate descriptions of matter than measurements. To get the description right make your measurements precise.
How do you keep your measurements consistent even if you are not precise or accurate?
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!
A measurement that is accurate is one that?
The measurement that is accurate is one that is precise. These are also commonly titled accurate measurements in the books.
Explain how a series of measurements can be precise without being accurate?
yes
Are precise measurements always accurate?
No. A broken clock gives a very precise time, but most of the time it is wrong.
What three steps can you take to ensure that measurements are both accurate and precise?
you can predict
Why is it important to both accurate and precise when you make measurements?
Sh*t means Feces or Faeces
Why is it important to be both accurate and precise when makeing measurements?
Sh*t means Feces or Faeces
How can a measurement be accurate but not precise?
Precision: how close measurements are to each other Accuracy: how close measurements are to the "true" or accepted value. If you do 3 trials of an experiment and you get 1.00 grams, 1.01 grams, and 1.03 grams as your answers but the real value was supposed to be close to 6.79 grams, your data was precise but not accurate.
What three steps can you take to insure that your measurment are both accurate and precise?
you can predict, estimate or use mathematical tools to make sure your measurements are precise and accurate i improved this answer i didn't change anything except for the punctuation i am not sure if this is right!!
What is the meaning of 'scientific?
Precision is defined as how close measurements are to each other. Example: 4.3, 4.4, 4.4 are precise because they are close to each other. If the "correct" answer is 4.4, they are also accurate. If the "correct" answer is 4.0, they are not very accurate, but they are still precise.
