Question

Write a note on accuracy and precision.

Answer 1

Accuracy in Measurements:

1. Measurement is the base of all experiments in science and technology. The value of every measurement contains some uncertainty. These uncertainties are called ‘Errors’.

2. The difference between the real value and the observed value is called an error.

1. Accuracy: Accuracy is the closeness of a measured value to the actual value or true value.
2. Precision: Precision is the closeness of two or more measurements to each other.
