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.Precision and accuracy are two indices of observational error. Precision is how near a collection of measurements is to its true value, whereas accuracy is how close the measurements are to one other. Precision, in other terms, is a description of random errors and a measure of statistical variability.If you weigh a body weighing 20 kg and obtain 17.4,17,17.3, and 17.1, your weighing scale is exact but not particularly accurate. If your scale returns values of 19.8, 20.5, 21.0, and 19.6, it is more accurate but not particularly precise.To learn more about Accuracy visit:https://brainly.com/question/14244630#SPJ9
