Question

Which one of the following is an effective way to reduce systematic errors in an experiment?

Options

• Taking the mean of a large number of readings

• Using instruments with the smallest least count only

• Calibrating instruments against a standard and correcting zero errors

• Ignoring all readings that differ from the expected value

Answer 1

Calibrating instruments against a standard and correcting zero errors

Explanation:

Systematic errors can be reduced by proper calibration, correct setup of instruments, and applying known corrections, not simply by averaging more readings.
