Experimental error is the difference between measurements, which deviates from a true value. 

Experimental Error

Error can be grouped into 2 major categories: Random error and Systematic error

Concept #1: Experimental Error

Calculating percent error allows a chemist to determine the amount of precision in their calculations. 

Concept #2: Random Errors

Concept #3: Systematic Error
