Which set of data is best described as accurate and precise when compared to an accepted value of 125? a..130, 125, 109, 210 b..122, 126, 121, 123 c..125, 100, 109, 200 d..190, 190, 191, 192

Answer : The correct option is, (B)122, 126, 121, 123

Explanation :

Accuracy is defined as the closeness of a measured value to a standard or known value.

For Example:

If the mass of a substance is 66 kg and one person weighed 61 kg and another person weighed 75 kg. Then, the weight measured by first person is more accurate.

Precision is defined as the closeness of two or more measurements to each other.

For Example:

If you weigh a given substance five times and you get 2.5 kg each time. Then the measurement is said to be precise.

Level of precision is determined by the maximum number of decimal places.

As we are given that the actual value is 125. So, 122, 126, 121, 123 are accurate and precise when compared to an accepted value of 125.

Hence, the correct option is, (B)122, 126, 121, 123
