Open interview textual analysis for evaluating closed-ended questionnaire

In order to go on with the study of differences between open and closed-ended answers we want to overcome the simple univariate comparison to arrive at the study of relations between open and closed-ended alternatives. The coding procedure of the open answers texts is made by means of both the manual post-coding and the textual analysis techniques. Since there is the possibility of observing open and closed-ended information taken from the same respondents, the aim of this work is to understand differences in the frequencies collected with the two data collecting tools and new methods of analysis are proposed.
