The type of error, which is produced by a faulty measuring instrument is called
Correct answer: D. Systematic error
- A. Logical error
- B. Random error
- C. Personal error
- D. Systematic error
Explanation
The correct answer is systematic error. Systematic errors are errors that consistently occur in the same direction whenever a particular measurement is made. This type of error can be caused by a faulty measuring instrument, such as a scale that is not calibrated correctly. In contrast, logical errors are related to incorrect reasoning, random errors are unpredictable fluctuations, and personal errors are due to human mistakes. Understanding the source of error is crucial in scientific measurement and experimentation.

About Errors and Significant Figures
Measurement errors include random and systematic effects, absolute, fractional and percentage uncertainty, and the precision shown by significant figures. Questions apply rounding rules and uncertainty propagation in addition, subtraction, multiplication and division, while distinguishing accuracy from precision and uncertainty from an actual mistake.
