Accuracy is how close a reported measurement is to the true value being measured. Resolution is the smallest change that can be measured. ... Finer resolution reduces rounding errors, but doesn't change a device's accuracy. However, resolution that is too coarse may add rounding errors.

Is it better to have accuracy or precision?

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.

How resolution affects accuracy and precision?

Accuracy: The error between the real and measured value. ... Precision: The random spread of measured values around the average measured values. Resolution: The smallest to be distinguished magnitude from the measured value.
