  4. What’s the difference between accuracy and precision? • The dictionary definitions of these two words do not clearly make the distinction as it is used in the science of measurement. • http://honolulu.hawaii.edu/distance/sci122/SciLab/L5/accprec.html

  5. Accurate means "capable of providing a correct reading or measurement." In physical science it means 'correct'. A measurement is accurate if it correctly reflects the size of the thing being measured.

  6. Precise means "exact, as in performance, execution, or amount. "In physical science it means "repeatable, reliable, getting the same measurement each time."
