Explanations of the different types of exercises can be found in the Preface. In summary, the objective is to provide four types of exercises:

Planning,After the definition of the experiment, the planning takes place. The definition determines the foundation for the experiment — . the experiment is conducted — while the planning prepares for . the experiment is conducted.

Analysis and Interpretation,After collecting experimental data in the operation phase, we want to be able to draw conclusions based on this data. To be able to draw valid conclusions, we must interpret the experiment data. Quantitative interpretation may be carried out in three steps, as depicted in Figure 15.

egins with accepting that there is a range of different ways of interpretation. It is concerned with discovering causes noticed by the subjects in the study, and understanding their view of the problem at hand. The subject is the person, which is taking part in an experiment in order to evaluate an object.

Without measurements, it is not possible to have the desired control and therefore an empirical study cannot be conducted.

Until now, this meant selecting a text from another discipline, usually psychology, and augmenting it with journal or confer­ ence papers that provide students wit
