Webb1st step. All steps. Final answer. Step 1/3. Explanation: Systematic errors are errors that are consistent and repeatable, usually arising from a flaw in the experimental design, equipment, or method. These errors can lead to inaccurate or biased results. Random errors, on the other hand, are unpredictable and fluctuate in magnitude and direction. WebbFig. 1.
