In a measurement, if the error is systematic, what can be said about the results? (2020)

Step 1: Understand what a systematic error is. It is a consistent, repeatable error that occurs in the same direction every time you measure.
Step 2: Recognize that systematic errors can come from faulty equipment, incorrect calibration, or consistent mistakes in measurement techniques.
Step 3: Realize that because systematic errors are consistent, they will always push your results away from the true value in the same way.
Step 4: Conclude that if your measurement has a systematic error, your results will be biased, meaning they will not accurately reflect the true value.

Systematic Error – A consistent, repeatable error associated with faulty equipment or a flawed experiment design that skews results in a specific direction.
Bias in Measurement – The tendency of a measurement to deviate from the true value due to systematic errors, leading to inaccurate conclusions.
