However, it can be reduced by making measurements with instruments that have better precision and instruments that make the measuring process less qualitative. Sources Of Error Examples Because systematic errors result from flaws inherent in the procedure, they can be eliminated by recognizing such flaws and correcting them in the future. What are some sources of error in synthesis of alum from aluminum foil? The idea here is to give you the formulae that are used to describe the precision of a set of data.

Recorded values should have at least one more place than the smallest division on the scale of the instrument. Types Of Sources Of Error Precision - relatively low indeterminate error.

- reproducibility. - high precision means a number of readings or trials result in values close to the same number.
