In this question the students had to give answers about the educational status
of their father and mother, choosing among five study levels. In the results showed
to the tables below, level 1 (primary school) and level 2 (Junior High school) are
put together, because only one parent appeared with education of level 1. It has
also become clear that there is a predominance of parents who possess a university
degree (85,2% for the father and 84,9% for the mother)
