Accuracy or exactness is the manner by which our answer is close to the one that is desired,an example is that of a high jumper that jumps to the accurate desired height for a gold medal during a competition. The precision of an estimation implies getting the result no matter the number of times one tries. An example is throwing a dart and hitting the bull's eye. So, no matter the number of times one throws the dart and it hits the spot where the Bulls eye is, it is considered as a precise throw.
