Suppose that two students perform a titration experiment multiple times, resulting in the average concentrations reported here. Student A 0.125 0.008 M Student B 0.12 0.03 M The more precise work was done by Choose... because Choose.... Choose... that student has fewer significant figures reported in their average. that student found a higher average concentration. that student's data has a larger standard deviation. that student's data has a smaller standard deviation.
