Enter the measured value and the true value into the calculator to determine the error value. This calculator helps in assessing the accuracy of measurements.
Variable Error Formula
The following formula is used to calculate the error value.
Error Value = Measured Value - True Value
Variables:
- Error Value is the difference between the measured value and the true value.
- Measured Value is the value obtained from the measurement process.
- True Value is the actual value of the quantity being measured.
To calculate the error value, subtract the true value from the measured value.
What is Variable Error?
Variable error is the difference between a measured value and the true value of the quantity being measured. It is an indication of the accuracy of the measurement and can be positive or negative, depending on whether the measured value is greater or less than the true value. Understanding the error in measurements is crucial for precision in scientific experiments, engineering, and quality control processes.
How to Calculate Variable Error?
The following steps outline how to calculate the Variable Error.
- First, determine the measured value.
- Next, determine the true value of the quantity being measured.
- Use the formula to calculate the error value: Error Value = Measured Value – True Value.
- Finally, compare the error value with the acceptable range of error for your application to assess the accuracy of the measurement.
- 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.
Measured Value = 105 units
True Value = 100 units
