Final answer:
Precision refers to how close measurements are to each other, while accuracy refers to how close measurements are to the target value. In an archery context, low precision and low accuracy mean the arrows are scattered and far from the target, while high precision and high accuracy mean the arrows are tightly grouped and hit the target.
Step-by-step explanation:
The question pertains to the concepts of precision and accuracy in measurements, often highlighted in scientific experiments or tasks such as archery. The terms low precision, low accuracy, high precision, and high accuracy describe different possible outcomes of these measurements. In an archery analogy, these terms can be understood as follows:
- Low precision, low accuracy: Arrows are scattered and do not hit near the target consistently, nor do they group together.
- High precision, low accuracy: Arrows are grouped tightly together but are not near the target, indicating consistent shots that are consistently off target due to a systematic error.
- Low precision, high accuracy: Arrows are not grouped closely but are generally centered around the target, indicating that the shots are on average correctly aimed but inconsistently executed.
- High precision, high accuracy: Arrows are grouped tightly and hit the target, indicating consistent and correct shots.
In a lab setting, scientists strive for measurements that are both highly precise and accurate to ensure reliable and replicable results.
