Notice that the Descriptive and Inferential Statistical steps (steps 7 and 8) are integral to the overall experimental design process. It is absolutely vital, therefore, that you decide on your statistical approach, both how you are going to convey (i.e. your summary figure or table) and analyse your data (Descriptive Statistics and Inferential Statistics, respectively) before you perform your experiment! It is fundamentally unacceptable to complete your experiment, obtain your data, and then scratch your head wondering what statistical strategy you need to adopt to analyse your data; all this demonstrates is very poor experimental technique. (At this point refer back to Example 1 in the Foreword.)
