It is easier to determine precision because all you need are your measurements or data and no knowledge of whether your data are a true representation of whatever phenomenon you are studying. For example, suppose you wish to measure the boiling point of a liquid, so you heat the liquid slowly and record at what temperature the liquid begins boiling. You do this several times and record boiling points of 76.5, 76.2, 76.3 and 76.3 degrees. The data seem very precise meaning the values are close together and reproducible. If your thermometer is off by 5 degrees, however, your data are completely inaccurate, but you would have no way of knowing this. To determine the accuracy of your data you would need to measure the boiling point by several different methods, for example using an electronic thermometer or simultaneously heating with the same heating apparatus a substance with a known boiling point for comparison.

what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
What is the difference between accuracy and presicion?
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
What is a prescribed decimal place called?
It is a specified degree of accuracy or precision.
How are accuracy and precision used when communicating deisgn ideas?

What word means the same as the word accuracy?
correctness rightness exactness precision
What does the precision of an instrument determine?
the answer is you have to use the right instrument on somthing to get the right answer
Does the speedometer have poor precision or poor accuracy?
Poor precision. Precision refers to the consistency of repeated measurements, while accuracy refers to how close a measurement is to the true value. If a speedometer consistently shows a speed that is off by a fixed amount from the actual speed (e.g., always reads 5 mph higher), it has poor accuracy. If it fluctuates widely even for the same speed, it has poor precision.
Does standard deviation give a measure of accuracy or precision?
precision
What is accuracy and precision and the difference between them?
The term accuracy describes how far your observation/measurement is from the correct result. Precision describes how repeatable your results are, regardless of their accuracy..
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 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.
What is precision?
Precision is a writer's attention to accuracy in world choice.
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.
What is the definition of precision?
precision is a writers attention to accuracy in word choice. (apex)
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.
Does percent uncertainty measure accuracy?
Accuracy STD on the other hand measures precision.
