Study Notes
Measurement Concepts
- Measurements should aim for minimal errors, with a focus on precision and accuracy.
- Precision refers to the consistency of measurements, while accuracy indicates how close a measurement is to the true value.
Examples of Precision and Accuracy
- Example 1: The first person hits all arrows at the center, demonstrating both precision and accuracy.
- Example 2: The second person hits arrows in the same spot but not at the center, indicating precision without accuracy.
- Example 3: The third person’s arrows are scattered and far from the target, showing neither precision nor accuracy.
Definitions
- Accuracy: Closeness of a measured value to the actual or true value.
- Precision: Closeness of multiple measurements to one another, regardless of their closeness to the true value.
Importance of Accuracy
- Accuracy is prioritized in measurements to ensure that results are meaningful and reliable. Measured values should consistently approach the true value to enhance validity.
