It is best to think of this in terms of a shooting target, when the bullet hits close to the bulls-eye, this is accuracy. In other words it is how close your result is to what it is supposed to be. Precision is about the grouping, if you fir 5 shots and one hits the bulls-eye, then on hits far above it, one below it, one to the left, and one to the right, they are not close and therefore your precision is off. However even if you hit as far from the bulls-eye as possible, but all five bullets hit in the same area, then this is precision. In other words if all of your results of your experiment always turn out about the same, it is precise.

How are accuracy and precision alike?
"Precision" is high when you get the SAME answer every time. Accuracy is high, when you get the CORRECT answer. You can hit a target in the same place everytime which is very HIGH precision; however, if that place is not the "Bulls Eye", your accuracy is lousy.
Which is better precision or accuracy of the experimental specifc heats detemined for your metal sample?
Accuracy because it tells us how close our value is to the accepted/expected value rather than precision that only describes reproducibilty and closeness of results to One another.
How are accuracy and precision used when communicating design ideas?
Its used to help keep objects as close or precise as possible. Helps others to understand you measurements.
What are the benefits of using automated techniques for manufacturing electric circuits?
I high degree of precision, accuracy and speed as well as reduced waste due to manufacturing errors.
What does accuracy and precision mean?
Precision measurements are those which are repeatable - so all measurements are clustered around the same value. An accurate measurement is where you are close to the true value. A measurement can be precise but not accurate. If you have a piece of string which is 75cm long. You measure it and come up with values of 60cm, 60.5cm and 59.5cm - your measurements are precise but not accurate. See also 'The Story of Measurement' by Andrew Robinson.

Define accuracy and precision?
Accuracy and precision are synonyms. They both mean without error, they are exactly right, No more and no less.
What is precision?
Precision is a writer's attention to accuracy in world choice.
Can accuracy depend on the precision of the instrument?
Yes, accuracy can depend on the precision of the instrument. The precision of an instrument determines the level of detail and resolution in measurements, while accuracy refers to how close the measured value is to the true value. Higher precision can improve the accuracy of measurements by reducing random errors, but it does not guarantee accuracy if there are systematic errors present in the instrument.
What is the definition of precision?
precision is a writers attention to accuracy in word choice. (apex)
Are precision and accuracy the same?
No because precision is when you trie to put your efeert toit
Is accuracy or precision related to standard error?
Standard error is a measure of precision.
How would one compare bike insurance?
One would compare bike insurance by putting them side by side and then going through each detail with accuracy and precision. The one that is better for you is the one you should use.
Is accuracy a measure of how close an answer is to the actual or expected value?
Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.
What is the difference between the accuracy of measurements and the precision of measurements?
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
Does percent uncertainty measure accuracy?
Accuracy STD on the other hand measures precision.
Does standard deviation give a measure of accuracy or precision?
Standard deviation gives a measure of precision, not accuracy. It quantifies the amount of variation or dispersion of a set of data points around the mean. Accuracy refers to how close a measurement is to the true value, while precision refers to how close repeated measurements are to each other.
Do precision and accuracy mean the same thing in science?
Precision and accuracy do not mean the same thing in science. Precision refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the correctness of a single measurement. It is determined by comparing the measurement against the true or accepted value.
