EVERYDAY SCIENCE

Detailed explanation-1: -The accuracy of an experiment, object, or value is a measurement of how closely results agree with the true or accepted value.

Detailed explanation-2: -The accuracy of an experimental value is best determined by the average value of multiple measurements where xi represents a measurement and n is the number of measurements.

Detailed explanation-3: -Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other.

Detailed explanation-4: -The ability of an instrument to measure the accurate value is known as accuracy. In other words, it is the the closeness of the measured value to a standard or true value. Accuracy is obtained by taking small readings. The small reading reduces the error of the calculation.

Detailed explanation-5: -Accuracy is how close a given set of measurements (observations or readings) are to their true value, while precision is how close the measurements are to each other. In other words, precision is a description of random errors, a measure of statistical variability.
