Q7. The figure below represents the bull's eye target for an archer. The black dots represent where the archer’s arrows hit. How can this archer be described?

Background

Topic: Precision and Accuracy in Measurements

This question tests your understanding of the difference between precision and accuracy, which are important concepts in scientific measurements and data analysis.

Key Terms:

• Accuracy: How close a measured value is to the true or accepted value.

• Precision: How close repeated measurements are to each other, regardless of whether they are close to the true value.

Step-by-Step Guidance

1. Examine the pattern of the black dots (arrows) on the target. Are they close together, or are they spread out?

2. Consider where the cluster of arrows is located relative to the center (bull's eye) of the target. Are they near the center, or off to one side?

3. Recall that high precision means the arrows are grouped closely together, while high accuracy means the arrows are close to the bull's eye.

4. Think about which description best fits the pattern shown: precise, accurate, both, or neither.
