Why does accuracy and precision matter?
Accuracy is used to assess just how well the average measurement of multiple measurements stacks up against the standard measurement of the same item or the true value. Precision can be viewed as a definition of how close various measurements are to each other.
What is important precision or accuracy?
Both accuracy and precision are equally important in order to have the highest quality measurement attainable. For a set of measurements to be precise, there is no requirement that they are accurate at all. This happens because as long as a series of measurements are grouped together in value, then they are precise.
