Homework Statement
You are asked to find the weight of a paper clip as accurately as possible and given ten paper clips and a scale that has a precision of 0.1 g. (A paper clip weighs about 1 g.) Which of the following proceedures would give you the most precise measurement the weight of a paper clip?
- Weigh each paper clip individually, average the values and calculate the standard error.
- Place all ten paper clips on the scale at once, then divide the value and the precision of the scale by ten.

The Attempt at a Solution
Precision is how close the measured values are to each other. With this being said procedure two would provide the most precise measurement. Procedure one would be much more accurate because it is measuring each paper clip individually to find how close the measurement of the weight is to the actual weight (1.0g). In procedure two all ten paper clips are measured at once meaning the value of the weight divided by 10 would be the average.I am not sure if my reasoning is correct. Any thoughts?
