Answer:
Precision refers to the dispersion of the set of values obtained from repeated measurements of a magnitude
Accuracy refers to how close to the actual value the measured value is
The resolution of a sensor (for example) is the smallest change in the magnitude of input seen in the magnitude of output
Explanation:
Precision is defined as the degree of coincidence between the independent results of a measurement, obtained under stipulated conditions, whether repeatability, reproducibility or intermediate. Generally, it is expressed in numerical terms when it comes to dispersion measures, for example, in the standard deviation or variance. Therefore, if there is a smaller distance in the distribution of each of the results, it means that there is greater precision.
On the other hand, the International vocabulary of fundamental and general metrology terms (VIM) defines the term accuracy as the degree of concordance between the result of a measurement and a true value of the measurand. This term is qualitative. If the measurement is closer to the true value it means that it is accurate. According to UNE 82009-1, equivalent to ISO 5725-1, the term accuracy can be described as follows: Accuracy = Veracity + Accuracy
Resolution: refers to the fineness of visible details for example in an image. In the case of aerial digital photographs, this concept is related to (Ground Sample Distance), which is the distance that corresponds to each pixel in reality. Therefore, the lower the GDS (the smaller the land area represented by each pixel), the greater the details that can be captured and the higher the resolution
