  1. 1. how close the measurement is to its value
  2. 5. Errors caused by factors we can’t control, like tiny temperature changes in a room. They happen when a measurement is made. The effect is reduced by repeating and averaging.
  3. 8. Errors caused by inaccurate equipment or by problems with a method or observation technique. Resolved by changing method.
  4. 9. exactness
