a teacher divides her class into groups and assigns each group the task of measuring the mass of the same object three times. the teacher already knows that the mass of the object is 25 g. based on the results each group records, which group makes the most precise measurements of the object? 3 of 3 questions group d: 20.0 g, 25.0 g, 30.0 g group c: 32.1 g, 35.0 g, 25.0 g group a: 28.5 g, 28.4 g, 28.5 g group b: 25.5 g, 25.0 g, 24.8 g

Answer

Answer:

D. Group B: 25.5 g, 25.0 g, 24.8 g

Explanation:

Step1: Understand precision concept

Precision refers to how close a set of measurements are to each other.

Step2: Analyze Group A

Measurements are 28.5 g, 28.4 g, 28.5 g. They are close to each other but far from 25 g.

Step3: Analyze Group B

Measurements 25.5 g, 25.0 g, 24.8 g are close to each other and close to 25 g.

Step4: Analyze Group C

Measurements 32.1 g, 35.0 g, 25.0 g have large differences among them.

Step5: Analyze Group D

Measurements 20.0 g, 25.0 g, 30.0 g have large differences among them. So Group B has the most precise measurements.
