Chapter 1: Problem 4

4\. Constant systematic error is usually caused by mis-calibration. a. true b. false

Short Answer

Expert verified
a. true

Step by step solution

01

Understanding systematic error

Systematic errors are consistent, repeatable errors associated with faulty equipment or flawed experiment design.
02

Determine the cause of systematic error

One common cause of systematic error is the mis-calibration of measurement instruments. Mis-calibration can cause the readings to consistently offset from the true value.
03

Interpret the statement

The statement says that a constant systematic error is usually caused by mis-calibration. Since mis-calibration is a common cause of systematic errors, the statement is correct.
04

Choose the answer

Based on the understanding, the correct answer to the question is 'a. true'.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Mis-calibration
Mis-calibration is when a measurement instrument does not read the true value due to incorrect adjustment. This error is predictable and consistent.

It can happen in various ways:
  • Instruments aging over time and drifting away from the standard settings.
  • Initial improper calibration against faulty or inaccurate references.
  • Environmental factors like temperature changes affecting the instrument's accuracy.
Mis-calibration leads to systematic errors because the deviation from the true value remains constant, influencing all measurements equally.
Measurement Instruments
Measurement instruments are devices used to quantify physical quantities, like length, temperature, or pressure.

Examples include:
  • Rulers and calipers for measuring length.
  • Thermometers for measuring temperature.
  • Pressure gauges for measuring pressure.
Ensuring accuracy in these instruments is crucial for reliable results. Regular calibration and maintenance are necessary to avoid systematic errors.

Another important aspect is choosing the right instrument for the measurement. Each instrument has a specified range and precision level. Using an incorrect instrument can also lead to errors.
Error Analysis
Error analysis helps identify and quantify errors in measurements. It is essential to ensure the accuracy and reliability of experimental results.

Types of errors:
  • Systematic Errors: Consistent, repeatable errors due to mis-calibration or flawed experimental design. These can be identified and corrected.
  • Random Errors: Errors that vary unpredictably from measurement to measurement. They can be reduced by averaging multiple measurements.
In error analysis, it's crucial to:
  • Identify the source of errors.
  • Understand the nature of the errors (systematic vs. random).
  • Use proper statistical methods to minimize and account for the errors.
Error analysis enhances the credibility and accuracy of scientific experiments and results.
