FAQs on Fun Video: Accuracy & Precision Video Lecture - JEE
| 1. What is the difference between accuracy and precision? |  |
Ans. Accuracy refers to how close a measurement is to the true or accepted value, while precision refers to how close multiple measurements of the same thing are to each other.
| 2. How do you calculate accuracy? | |
Ans. To calculate accuracy, you subtract the measured value from the true value and divide that by the true value. Then you multiply that result by 100 to get a percentage.
| 3. What is an example of a precise measurement that is not accurate? | |
Ans. An example of a precise measurement that is not accurate is if you measure the length of a pencil 10 times and get the same measurement each time, but that measurement is off by 2 centimeters from the true length of the pencil.
| 4. How can you improve accuracy and precision in measurements? | |
Ans. To improve accuracy, you can use more precise measuring tools, take more measurements, and eliminate sources of error. To improve precision, you can use more precise measuring tools, take more measurements, and ensure that all measurements are taken under the same conditions.
| 5. What is the significance of accuracy and precision in scientific experiments? | |
Ans. Accuracy and precision are important in scientific experiments because they ensure that the results obtained are reliable and can be replicated. Without accurate and precise measurements, it is difficult to draw conclusions or make predictions based on the data collected.
