Accuracy and Precision
- Accuracy is the closeness of a particular estimate of a parameter to the true value of that parameter
- Precision is the reproducibility of our measurement irrespective of how close it is to the true value
A good analogy is with the grouping of a player’s darts on a dartboard, where the ideal target is the bullseye at the center of the board.
- Systematic error is reproducible inaccuracy. Thus the grouping of darts on the left-hand board above is systematically biased toward the upper left of the board.
- Random error is irreproducible error. Thus, the grouping on the right-hand board above is neither reproducible (precise) nor accurate.
