Study Notes
Accuracy
- Definition: Measurement closeness to the true or accepted value.
- Important for determining the validity of a measurement or result in scientific studies.
- Example: A thermometer reading 100°C when the actual temperature is 100°C demonstrates high accuracy.
Precision
- Definition: Closeness of a series of measurements to one another, indicating consistency.
- Important for reliability in repeated experiments or observations.
- Example: A scale consistently showing 50g for multiple measurements of the same object, even if the true weight is different.
Comparison of Accuracy and Precision
- Accuracy assesses proximity to the true value, while precision evaluates consistency across multiple measurements.
- Both are essential for effective data interpretation and scientific integrity.
