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 is the difference between precision and non-precision casting techniques?
nothing
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.
What is the difference between accuracy and precision and which one is more important to scientific measurement?
To be accurate is to be correct, for example, if you say it will rain tomorrow and it does rain tomorrow, then your prediction was accurate. Precision means to give a finely detailed measurement or observation, rather than an approximation. In the case of the weather prediction, a precise prediction might be on the order of, it will rain a total of 1.68 inches of rain, tomorrow. Such a prediction might or might not be accurate, but if it is, then it is also precise, much more precise than merely predicting that it will rain. Precision includes the concept of accuracy. An observation that is precise but inaccurate is useless; precision is only valuable when it is also accurate. Scientists cannot really choose between accuracy and precision since both are necessary for science to succeed, but accuracy is more fundamental. Something that is approximately correct is worth more than something that is very detailed, but wrong.

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 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?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
What was the precision of Tycho Brahe's measurements in Denmark?
Tycho Brahe (and his assistants) recorded measurements at his observatory on the island of Ven with an accuracy of up to 4 seconds of arc. Most of his measurements were angular measurements between celestial objects (between stars, between planets and stars and between planets).
What is a precise measurment?
A precise measurement is an exact measurement.How long,how tall how wide. EXAMPLE-12X5X24Precision refers how close measurements of the same thing are to each other. A precise measurement is one that is similar or the same as previous measurements. A precise measurement does not need to be accurate.precise measurements may not be accurate but will agree with each other. Characteristic of precision is low standard deviation. It is not in all cases proof of accuracy though
What is the difference between precision and non-precision casting techniques?

What is The level of closeness between multiple measurements of the same quantity is called?
Precision
The level of closeness between multiple measurements of the same quantity is called?
precision
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.
