Two students A and B measured the diameter of a wire in mm.

Data A: 1.57, 1.58, 1.43, 1.50, 1.42 Average of data A: 1.50

Data B: 1.60, 1.59, 1.59, 1.60, 1.62 Average of data B: 1.60

Actual diameter is known to be 1.50 mm.

Whose data is more precise?

• A, because the values in his data are close to each other

• B, because the values in his data are close to each other

• A, because the average value is close to the actual value

• B, because the average value is close to the actual value
