Answer
### a. Accuracy: If the measurements are close to the center of the target, they represent high accuracy. If they are far from the center, they represent low accuracy.### b. Precision: If the measurements are tightly grouped together, they represent high precision. If they are spread out, they represent low precision.
Explanation
## Step1: Define Accuracy and Precision### Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close the measurements are to each other, regardless of whether they are close to the true value.## Step2: Evaluate Accuracy### To evaluate accuracy, we need to determine how close the measurements on the target are to the center (the true value). If the measurements are close to the center, they are accurate.## Step3: Evaluate Precision### To evaluate precision, we need to assess how close the measurements are to each other. If the measurements are tightly clustered together, they are precise.#
