Quizplus · Accepted Answer

The most precise set of measurements is the one with the smallest range of values. The range of values in set D (1.513 g, 1.517 g, 1.512 g) is the smallest, with a difference of only 0.005 g between the highest and lowest measurement. Sets A, B, C, and E have ranges of 0.020 g, 0.063 g, 0.074 g, and 0.048 g, respectively, which means they are less precise than set D. Therefore, set D is the most precise.
