precision reflects our certainty of reliably achieving it. With these two principles in mind, we can shoot for the stars and be confident of hitting them every time.精确度是我们追求的最终目标,而精密度反应了我们能达到最终目标的可能性.二者的有机结合,才能使得我们最终成功.故答案为Accuracy reflects our ce...
129.4 is a number that is less precise than 129.43939480But if the possible range of error in our measurement is 10%, then our measurement of 129.4 OR our measurement of 120.2939480 both could be expressed as +/- 12 (since 12 is 10% of 120). This means that the range of accuracy of...
【题目】What's the difference between accuracy and precision?As the story goes, the legendary marksman (神射手) William T ell was forced into a cruel challenge by a corrupt lord. William's sonwas to be killed unless William could shoot an apple off his head. William succeeded, but let's...
The bullseye example is the most common way to show the difference between accuracy and precision. Think of throwing darts at a bullseye. The goal is to be both accurate and precise. In other words, to hit the bullseye as frequently as possible. If you’re simply accurate, that means you...
significant digits to which a value has been reliably measured". If on several tests the temperature sensor matches the actual temperature while the actual temperature is held constant, then the temperature sensor is precise. By the second definition, the number 3.1415 is more precise than the ...
Frequently Asked Questions What is the difference between accuracy and precision? Accuracy is how close measurements are to an accepted or true value. Precision is how close measurements of the same type are to each other.
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...
