Can something be both accurate and precise?

Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy. That means it is possible to be very precise but not very accurate, and it is also possible to be accurate without being precise. The best quality scientific observations are both accurate and precise.

When would a measurement be both accurate and precise?

In simpler terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be accurate if their average is close to the true value of the quantity being measured, while the set can be said to be precise if the values are close to each other.

Can accuracy and precision be the same?

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.

What is the difference between accurate and precise measurements?

Accuracy and precision are alike only in the fact that they both refer to the quality of measurement, but they are very different indicators of measurement. Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value.

Is the measurement accurate or precise?

Accuracy is a measure of how close a measurement is to the correct or accepted value of the quantity being measured. Precision is a measure of how close a series of measurements are to one another. Precise measurements are highly reproducible, even if the measurements are not near the correct value.

Can just one measurement be considered precise?

Explain your answers completely. · Yes, just one measurement can be considered accurate because you need several measurements to back up your observations to prove it to be precise, but it can be considered accurate because accuracy is defined as matching the value that is accepted.

Which measurement is more precise?

The accuracy of a measurement depends upon the size of the unit of measure being used. The smaller the unit, the more precise the measurement. For instance, a measurement rounded to the nearest sixteenth of an inch is more precise than a measurement rounded to the nearest eighth of an inch.

What makes a measurement precise?

Measurements are said to be precise if they yield very similar results when repeated in the same manner. A measurement is considered accurate if it yields a result that is very close to the true or accepted value. Precise values agree with each other; accurate values agree with a true value.

What is the difference between accuracy and precision?

The main difference between accuracy and precision is that accuracy refers to the degree to which the measurement or calculation conforms to the exact value. Accuracy is exactness, validity and perfection. While precision is the attribute of the calculation to be consistently reproduced.
