How do you improve accuracy in manual marking

• A. Sharp pencil
• B. Repeat measurements
• C. Protractor
• D. Set square

Answer: (B)

Reducing random error by repeating measurements. When you mark out a dimension or an angle, small slips, eye judgment, or reading a scale at an angle can introduce mistakes. By measuring more than once and comparing the results, you can spot any discrepancy and choose a result that’s consistent. If the readings match, you can proceed with confidence; if they don’t, recheck the measurement or take an average to settle on a more accurate mark. This direct approach tackles measurement error and improves reliability of the final mark. While a sharp pencil helps the line stay clear and tools like a protractor or set square aid with geometry, they don’t address the inconsistency that comes from a single measurement as effectively as repeating measurements.
