Accuracy is how close a measured item is to the actual or true value and precision is how close the measured items are to being the same. So you could weight 5 apples. If each apple weights 2 lbs and you said that the 5 apples weight a total of 10lbs you are determining the precision. Precision is independent of accuracy. Accuracy would be if you put all 5 apples on the scale at one time and knew a exact amount.
