Which is more important precision or accuracy?
Accuracy is something you can fix in future measurements. Precision is more important in calculations. When using a measured value in a calculation, you can only be as precise as your least precise measurement. … Accuracy and precision are both important to good measurements in science.
Can a measurement be precise but not accurate?
Yes, the unit of measurement can be precise but not accurate. Precision is referred as the closeness of two measurements to one another while accuracy refers to the closeness of the measurement from the standard or known value. Precision is independent from accuracy and may not be accurate.
What affects precision and accuracy?
Accuracy refers to how closely the measured value of a quantity corresponds to its “true” value. Precision expresses the degree of reproducibility or agreement between repeated measurements. The more measurements you make and the better the precision, the smaller the error will be.
