## When a test instrument is calibrated does it accuracy precision and reliability improve?

The answer is accuracy. That is when a test instrument is calibrated, its accuracy is improved. That is the result comes more close to what it is. The other factor will not be improved that is its reliability and precision remains the same.

## Which of the following measurements is the most accurate?

Explanation: Accuracy is defined as the closeness of the measurements to a particular value. Out of given options, the most accurate value is 40 meters as the chances of getting relative error is least. Precision is defined as how close the measurements to each other.২৮ সেপ্টেম্বর, ২০১৯

## How can we know if a measuring device is accurate?

In simpler terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be accurate if their average is close to the true value of the quantity being measured, while the set can be said to be precise if the values are close to each other.
