| Precision | Consistency and repeatability of measurements | Scale that always shows the same weight (e.g., 0.1 kg variation) |
| Accuracy | Closeness of a measured value to the true value | Thermometer consistently reads 2°C higher than actual temperature |
| Differences | Precision is about consistency; Accuracy is about closeness to the true value | Precision: Tight cluster; Accuracy: Center of the target |
| Scenarios | Various combinations of precision and accuracy | Accurate and precise, accurate but not precise, precise but not accurate |
| Practical Application | Requires calibration, control of conditions, and error consideration | Measurement instruments and experimental setups |
