This document contains questions about accuracy and precision as it relates to shooting targets and measuring weights. It asks the reader to identify examples that demonstrate high or low accuracy and precision based on different shooting and measurement scenarios. It also provides definitions for the terms "accuracy" and "precision" and asks the reader to apply these definitions in evaluating a target with bullet holes.
