Explain accuracy and precision in measurement. |
|
Answer» Solution :The accuracy of a measurement is a MEASURE of how close the measured value is to the true value of the QUANTITY. Precision tells us to what resolution or limit the quantity is measured. For example any digital WATCH that shows the time as 10:11:12 AM is very precise because it has least count of 1 SECOND. Any other digital clock has no second hand and it gives the time as 10:13 AM.The least count of watch is 1 minute which means that is less precise. If the digital watch runs several minutes slow then time measured with this watch has no accuracy but it is precise |
