4,1 TYPES OF RESEARCH Exist two basic criteria of Research of classification according to Vergara (2004), how much to the ways and how much to the ends, these if divide in other definitions. Our project how much to the ways of inquiry she is bibliographical, study of case, research of field and participant; how much to the ends it is exploratria and descriptive. We know that the half ones are which types of research resources that the project uses, and the ends are what the project intends in relation to the reality that it investigates. In definition of our research, how much to the ways we identify that it is bibliographical, therefore are developed on the basis of material published in books, magazines, periodicals and electronic nets being primary or secondary sources, is also a case study, therefore it has character of depth and detailing, is field research, therefore inquiry is carried through in the place where it occurs a phenomenon and it makes use of elements to explain it, it is participant, therefore the research is not depleted in the figure of the researcher takes part people implied in the problem under inquiry. How much to the ends it detaches to be exploratria, therefore if it carries through in an area where it has little accumulated knowledge, and is descriptive, therefore it displays the characteristics of the inquiry object. 4.1.1 Collection of data Exists many types of collection of data according to Roesch (2009, p.140): The main techniques of collection of data are the interview, the questionnaire, the tests and comment. Also it is possible to work with existing data in the form of archives, data base indices or reports. These are not ' ' criados' ' for the researcher and normally they are called of secondary data in contrast with the primary data that are harvested directly by the researcher.
