Experimental Planning

What is Experimental Planning?

Designing an investigation so that its results can answer the question asked. It means identifying the independent variable that is changed, the dependent variable that is measured, and the control variables that must be kept the same because they would otherwise also affect the measurement; choosing a sensible range and number of values; selecting and justifying apparatus; and identifying hazards with a specific precaution for each.

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