Question

Which statement best describes the effect of systematic errors on measurements?

Options

• They only increase the precision, but not the accuracy

• They can be removed by taking a large number of readings

• They shift all readings away from the true value in the same direction

• They cause readings to fluctuate randomly around the true value

Answer 1

They shift all readings away from the true value in the same direction

Explanation:

Systematic errors cause a consistent bias so that all measurements are either too high or too low by almost the same amount, which reduces accuracy.
