Systematic Error Formula
The following formula is used to calculate the systematic error:
SE = MV - TV
Variables:
- SE is the systematic error
- MV is the measured value
- TV is the true value
To calculate the systematic error, subtract the true value from the measured value.
What is Systematic Error?
Systematic error is a consistent, repeatable error associated with faulty equipment or a flawed experiment design. Unlike random errors, which are caused by unpredictable statistical fluctuations, systematic errors affect the accuracy of a measurement and can often be identified and corrected. Understanding and minimizing systematic errors is crucial for improving the reliability of experimental results.
How to Calculate Systematic Error?
The following steps outline how to calculate the systematic error:
- First, determine the true value (TV).
- Next, determine the measured value (MV).
- Use the formula SE = MV – TV to calculate the systematic error (SE).
- Finally, compare the systematic error with the acceptable limits for your experiment or measurement to assess the significance of the error.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
True value (TV) = 100 units
Measured value (MV) = 102 units
