Question

Define accuracy Precision and errors also Explain types of error with at least one elimination for each

Answer 1

Accuracy refers to the closeness of a measurement to the true value of the physical quantity. It indicates the relative freedom from error. As we reduces the error the measurements becomes more accurate.
Precision refers to the resolution or the limit to which the quantity is measured.
The error in a measurement is equal to the difference between the true value and the measured value of the quantity.
Different types of errors are :
1. Constant error
2. Systematic error
3. Random error
4. Least count error
5. Gross error
