Sources of=20 Error

Much=20 confusion surrounds this simple requirement you will have to meet = in most=20 labs. Here you = go! Understand and use=20 it.

DEFINITION: A source of error is a = limitation=20 of a procedure or an instrument that causes an inaccuracy in the=20 quantitative results of an experiment. A human error is not=20 considered a source of error under this definition. Students = should=20 strive to identify, understand, and limit sources of error in = their=20 procedures whenever possible.
