Differentiate between permissible and experimental errors

Permissible error: The amount of error that can be tolerated without invalidating the usefulness of the analytic result. It is generally 95% of the analytical error.

Experimental error: The error that may be caused due to human inaccuracies like a wrong experimental setup in a science experiment is called experimental error. It is unavoidable during the conduct of any experiment because of the falsifiability principle of the scientific method.
