What is meant by precision of the measurement?
Precision of a measurement represents the numerical values which represent the dimensions of the instrument measured more accurately.Precised values are nearer t accuracy with negligible error.
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 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 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.
Explain the illustration of precision and accuracy?
Precision is a measure of how much tolerance your observation has. If you measure time in an experiment as 1.7 +/- .3 seconds, then you are saying that the obervation is anywhere from 1.4 seconds to 2.0 seconds. On the other hand, if you say 1.70 +/- .05 seconds, you state a range of 1.65 seconds to 1.75 seconds. The second observation is more precise than the first. Accuracy is a measure of how correct a measurement is as compared with a standard. If the instrument that measured 1.7 seconds was actually 1.6 seconds, then it would have an accuracy error of .1 seconds. Precision is related to random error. Accuracy is related to systematic error.
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
What is a precision instrument?
Precision means accuracy. A precision instrument is a top quality one that is super-accurate. You can get an instrument that will just do the job, or you can spend extra money and get a precision instrument that will be perfect. Many measuring devices are precision instruments because they must be totally accurate.
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 meant by precision of the measurement?
Precision of a measurement represents the numerical values which represent the dimensions of the instrument measured more accurately.Precised values are nearer t accuracy with negligible error.
Precision and non-precision measuring instrument?
precision instrument: caliper, micrometer non-precision measuring instrument: your hand, a piece of string
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.
