Graphical representations of the questionnaire
The following results are obtained by performing a Multiple Correspondence Analysis (MCA) on the previous 20 variables. This method provides two important graphical displays, a representation of the individuals (surveyed people) and a representation of the categories (answers given by the surveyed people). The first two main axes of variability explain 10.77% of the information contained in the dataset (6.58% for the first factorial axis and 4.19% for the second one). In some cases the analyst may want to introduce supplementary quantitative variables.

Typology on the individuals
3.1
Choice of the number of clusters
The ascendant hierarchical clustering (AHC) lead to a partition made of 3 clusters. Those clusters are displayed in the following representations: a graphical representation of the individuals according to the cluster they belong to, a representation of the center of gravity of each group enhanced by a confidence ellipse, a representation of the individuals according to the cluster they belong to by the use of density curbs.
