Question

Which of the following statements is correct about significant figures and accuracy?

विकल्प

• Fewer significant figures mean greater accuracy

• The number of significant figures does not affect accuracy

• Greater the number of significant figures, greater is the accuracy

• Accuracy depends only on the number of measurements taken

Answer 1

Greater the number of significant figures, greater is the accuracy

Explanation:

The larger the number of significant figures in a measurement, the more precise and accurate the result. Using an instrument with a smaller least count increases the number of significant digits, thereby improving measurement accuracy.
