Sure, some students make mistakes, but mistakes are not sources of error. Calculation mistakes are something that students are expected to avoid. If there are mistakes in your calculations, these are not sources of error. A source of error is something that you could not plausibly expect to avoid. If you used equipment incorrectly or followed the procedures incorrectly, for example, these are mistakes-they are not sources of error. You can definitely find more significant sources of error to describe instead of round-off error. Even a cheap calculator provides at least 8 figures, whereas most first-year physics experiments yield results where only 2-3 of those digits are significant figures. This problem with this is that students almost never have enough precision in their answers for round-off error to be significant. Advice: Don’t write the phrase “human error” anywhere on your lab report. It may be okay if the nature of the error is human in origin (provided that it’s an inherent error and not a mistake), but it’s not okay to be express the error in vague terms. The problem with this phrase is that it’s way too vague.

Part of learning how to write a good sources of error section includes learning what not to do.įollowing are some common incorrect answers that students tend to include in their sources of error section. We will see examples of each in the remainder of this article. A mistake is something that affects results, which should reasonably have been avoided.An error is something that affects results, which was not plausible to avoid (given the conditions of the experiment) or account for.However, in physics, these two words have very different meanings: In everyday English, the words “error” and “mistake” may seem similar. provide examples of how to describe sources of error.describe common mistakes that students make in physics lab reports.learn how to identify sources of error for a physics experiment.
