Question

1. 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.

or

Place all ten paper clips on the scale at once, then divide the value and the precision of the scale by ten.

EXPLAIN WHY!

Explanation / Answer

Place all ten paper clips on the scale at once, then divide the value and the precision of the scale by ten


this way max error in each weight of paper clip = 0.1/10 = 0.01 gm

if we measure them indivisually possible error each time = 0.1 gm
