Systematic Error Formula:
From: | To: |
Definition: Systematic error (SE) is the difference between an observed value (O) and the expected or true value (E).
Purpose: This calculator helps identify consistent, predictable errors in measurements or experimental results.
The calculator uses the formula:
Where:
Explanation: A positive result indicates the observed value is higher than expected, while a negative result indicates it's lower.
Details: Identifying systematic errors helps improve measurement accuracy, calibrate instruments, and validate experimental methods.
Tips: Enter the observed measurement value and the expected or true value. The calculator will show the systematic error.
Q1: What causes systematic errors?
A: Common causes include instrument calibration issues, environmental factors, or procedural biases.
Q2: How is systematic error different from random error?
A: Systematic errors are consistent and predictable, while random errors vary unpredictably.
Q3: Can systematic error be eliminated?
A: While it can't always be eliminated, it can often be reduced through calibration and improved methods.
Q4: What units does systematic error use?
A: The error has the same units as your observed and expected values.
Q5: How do I determine the expected value?
A: The expected value may come from theoretical calculations, reference standards, or known accurate measurements.
