Calculating Percent Error Of Equipment
Evaluation – what if equipment errors are below 5%? It’s not necessary to suggest a change, but still comment on it to show that you’ve critically evaluated your equipment use. 16. Accuracy is a measure of how close the result of the measurement comes to the "true", "actual", or "accepted" value. (How close is your answer to the accepted value?)

Answered In Science Define equipment error and explain how to reduce it? If you measure the same object two different times, the two measurements may not be exactly the same. A typical meter stick is subdivided into millimeters and its precision is thus one millimeter. The examples below all have four significant figures: 0.06027 3.783 2.130 0.004083 6.035 x 105 Now check out the number of significant figures in the answers for each of the following: a fantastic read
