Accuracy Vs Precision Statistics. Using the percent. Precision describes the spread of individual shots about the center point of a group of shots.
Accuracy focuses on systematic errors ie. Lets look at a common analogy to illustrate the difference between accuracy and precision. The student of analytical chemistry is taught - correctly - that good precision does not mean good accuracy.
Imagine a scenario in which an experiment like a clinical trial or a survey is carried out over and over again an enormous number of times each time on a different random sample of subjects.
Accuracy refers to how close measurements are to the true. Using the percent. The student of analytical chemistry is taught - correctly - that good precision does not mean good accuracy. Value while precision refers to how close measurements are to each other.
