A Practical Example, Accuracy vs. Precision

For a practical example, consider measuring the length of a football field with a warped and kinked steel tape. Reading this tape may give repeated distances of very close to 100.009 yards. This would be a high-resolution set of measurements giving a precise measure of the length of the football field. It would still be considered wrong or inaccurate relative to a more rigorous measuring method such as using a better tape or another instrument.
