Final answer:
The preferred method of establishing an accurate target location is to use a system that is both precise and accurate, where the measurements are closely concentrated and near the true location.
Step-by-step explanation:
The preferred method of establishing accurate target location is to utilize a system that is both precise and accurate. Precision refers to how close multiple measurements are to each other, while accuracy refers to how close a measurement is to the true or accepted value. When considering a GPS system that attempts to locate a restaurant, the ideal scenario is when the GPS data points (each represented by the black dots on a bull's-eye) are concentrated closely together (high precision) and are also close to the center of the target (high accuracy).
If the dots are spread out far apart but close to the target's center, the GPS has high accuracy but low precision. Conversely, if the dots are closely concentrated but far from the target's center, it indicates high precision but low accuracy. The preferred scenario is represented by a pattern where the data points are both close together and close to the true location, ensuring that the GPS system reliably locates the target accurately and consistently over multiple attempts.
