In your own words, what is the difference between "accuracy" and "precision"? Give an example (your own example, no scales or dart-boards). Put your answer in the space below (for this and all other questions). This experiment will have you place some water into various pieces of glassware, read how much water the glassware says should be in the container, and then compare this reading to the actual volume of water in the piece. Describe how you will determine this...
