Question

If two measurements are very close to each other, then they are ____..

Answer 1

The correct answer is:

B) precise

Explanation:

Precision can be broken down into two pieces:

Repeatability - The variation observed when the same person measures the same thing repeatedly with the same device.

Reproducibility: The variation observed when different people measure the same thing using the same device.

If two measurements are very close to each other, this gives repeatability. If the measurements were made by different people, this gives reproducibility.

Accuracy, however, describes the difference between the measurement and the thing's actual value. This would not involve getting the same result repeatedly; it would be getting the correct value.

Answer 2

If two measurements are very close to each other, then they are precise. The correct answer is B.
