Question

a student measures the mass of a metal weight using three separate balances and collects the following data: 38.7g, 38.9g and 38.6g. The actual mass of the weight is 34.2 g. Evaluate the accuracy and precision of this student's measurements.

Answer 1

The values are precise because the values are close together but they are not accurate because they are all far from the true value.

What is the accuracy and precision?

The term accuracy refers to how much close to the true or the actual value that a measurement is. The precision refer to how close together the values that are obtained in a series of measurements are.

Now, we have the values that were obtained as; 38.7g, 38.9g and 38.6g. We can see that values are precise because the values are close together but they are not accurate because they are all far from the true value.
