Experimental Method

What is Experimental Method?

The sequence of steps, apparatus and conditions chosen to obtain a particular measurement or observation. Its advantages and disadvantages are judged against the task it was chosen for: the precision the result actually needs, the capacity and range required, the speed of the method, whether a quantity is collected directly, and the risks of leakage, breakage or human reading error. The same apparatus can be an excellent choice in one experiment and a poor one in another.

This definition is part of the Experimental Techniques and Chemical Analysis chapter in Cambridge O Level Chemistry.
