Which one of the following statement is not correct?a)It is not possib...
Introduction:
In the field of measurement, accuracy and precision are two important concepts. Accuracy refers to how close a measured value is to the true or accepted value, while precision refers to the level of consistency or reproducibility of repeated measurements. It is important to understand the difference between accuracy and precision to ensure reliable and meaningful measurements.
Explanation:
Statement a) It is not possible to have precise measurements which are not accurate:
This statement is not correct. It is possible to have precise measurements that are not accurate. Precision is related to the consistency and reproducibility of a measured value, whereas accuracy is related to how close the measured value is to the true value.
Example:
To better understand this concept, let's consider an example. Suppose you have a target and you are shooting arrows at it. If all your arrows hit the same spot, even if it is far from the center of the target, your shots are precise but not accurate. On the other hand, if your arrows are scattered around the center of the target, your shots are accurate but not precise. Ideally, you would want your shots to be both accurate and precise, meaning they hit close to the center of the target and are tightly clustered together.
Conclusion:
In conclusion, the statement that "It is not possible to have precise measurements which are not accurate" is incorrect. Precision and accuracy are distinct concepts in measurement, and it is possible to have precise measurements that are not accurate. Understanding the difference between accuracy and precision is crucial for reliable and meaningful measurements in various fields, including electrical engineering.
