Answer:
The given data are more precise than they are accurate
Explanation:
From the given measurements, we have;
The accurate mass = 34.75 g
The deviations from the accurate measurement is as follows;
34.2 g - 34.75 g = -0.55 g
33.75 g - 34.75 g = -1 g
35.0 g - 34.75 g = 0.25 g
34.69 g - 34.75 g = -0.06 g
For precision measurement, we find the average deviations as follows;
The sum of the deviations = -0.55 g - 1 g + 0.25 g - 0.06 g = -1.36 g
The average deviation = -1.36 g/4 = -0.34 g
For accuracy measurement, we find the average of the absolute deviations as follows;
The sum of the absolute deviations = 0.55 g + 1 g + 0.25 g + 0.06 g = 1.86 grams
The average absolute deviation = 1.86 g/4 = 0.465 g
Therefore, the magnitude of the average deviation is less than the magnitude of the absolute deviations, therefore, the given data are more precise than they are accurate
