I am testing out series of scales by weighing an object with a true weight of 5.000 g. I repeat the measurement 5 times and record the values the scale displays. Decide which scale is the most precise.

Scale 1 Scale 2 Scale 3 Scale 4 Scale 5
5.001 g 10.222 g 5 g 0.322 g 0.500 g
4.001 g 11.058 g 4 g 0.321 g 1.000 g
6.001 g 5.000 g 6 g 0.322 g 1.500 g
4.501 g 7.000 g 7 g 0.323 g 1.700 g
5.501 g 3.011 g 5 g 0.322 g 1.300 g
