''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.

Both accuracy and precision reflect how close a measurement is to an actual value, but they are not the same. Accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value. Measurements that are both precise and accurate are repeatable and very close to true values.

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 the difference between an accurate and a precise measurement?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
What is the difference between accuracy and uncertainty?
accuracy is when you KNOW something and uncertancy is when your not sure
What is the difference between Quality and Accuracy?
accuracy is the how well it is done. Quality is what something is worth.
How do you differentiate between accuracy and precision of data?
So accuracy is how close the mean is to the true value. Precision is how close all your values are to each other. If you have repeatable results you will see this straight away. Spiking samples with known amounts is a great way to find out if you have as much as you think you have i.e. checking the 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.
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..
What are accuracy and precision and what is the difference between accuracy and precision?
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
What is the difference between acurtate and precise?
An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.
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 the difference between an accurate and a precise measurement?

What is the difference between precision and non-precision casting techniques?

Does the speedometer have poor precision or poor accuracy?
Accuracy and precision mean the exactly the same thing in this context.
What differecne between the accuracy and precision?
Accuracy is how close the value that is measured to a true or standard value. While precision is referred as the degree of nearness of the measured values to one another in a repeated same value.
Does standard deviation give a measure of accuracy or precision?
precision
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 accuracy and precision and which is most important to scientific measurement?
Both accuracy and precision are important to scientific measurement. I'll try to explain the difference with a couple of illustrations. I should start by saying, sometimes the words are used interchangeably but they shouldn't be. I consider precision to mean resolution. That is how fine/small a reading you can get.Assume an electronic thermometer (digital display) can display answers to the nearest one hundredth of a degree. But, the thermometer isn't able to measure with that accurately. Maybe it's only accurate to the nearest whole degree. In this case the precision is greater than is supported by the accuracy of the device.Now take the opposite case where the thermometer is able to measure temperature accurately to one hundredth of a degree but the instrument can only display whole degrees. In this case the precision does not support the accuracy.Ideally the accuracy and precision of an instrument are the same but often that's not the case.
