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.
An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.
Accuracy and Precision is specification conforms to the correct value or a standard, and they are meaning the same thing of accurate or being exact, they're only difference is there spelling and they are defining each other.
precision and accuracy
accuracy. precision how closely the group of data are in relation to each other
Then they have precision but not accuracy.
Precision is how close your measurements are. Accuracy is how close your measurements are to the actual measurement.
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..
An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.
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.
The article at the link below should help you get a handle on the subtle differences 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.

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.
precision
Accuracy and precision are synonyms. They both mean without error, they are exactly right, No more and no less.
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.
Precision is a writer's attention to accuracy in world choice.
