Triangulation is used to indicate that two (or more) techniques or methods are used in the same study in an articulated manner to achieve their results. "The concept of triangulation is taken from navigation and topography techniques, which determine a single point in space from the convergence of measurements taken from two other distinct points."
Therefore, its purpose or purpose is the contrast of several data and methods that are focused on the same problem, so comparisons can be established. We can do that taking the impressions of different groups, in different contexts and temporalities, thus evaluating the problem with breadth, diversity, impartiality and objectivity.
What is Triangulation
Ruth and Finol (2009) in their research article entitled: Triangulation as an Analysis Procedure for Educational Research highlights the following:
Triangulation in social research has many advantages because using different methods, they act as filters through which reality is captured selectively. Therefore, it is convenient to collect the event data with different methods: if the methods differ from each other, in this way they will provide the researcher with a greater degree of confidence, minimizing the subjectivity that could exist in any act of human intervention.
That is why it is necessary to face the object of research from different prisms. Especially when the subject of study is broad and is influenced by various causes, which may or may not be interrelated. The practicality of the triangulation of the group is not only given by its multidisciplinary nature. This enriches the design of the tool for obtaining information (qualitative and / or quantitative), but also the joint and synchronous analysis of the data is feasible. obtained.
Types of triangulations and their definitions.
When referring to this type of triangulation, the authors propose the crossing of various strategies used to collect data. “Its objective is to verify the trends detected in a certain group of observations. The confrontation of the data can be based on space-time criteria and levels of analysis, ”they add.
In relation to the space-time criteria, the spatial refers to the fact that the study does not focus on populations located in the same place that refer to the same culture. But on the variability of working with subjects from different areas and the temporality has to see with the study of the phenomenon at different times.
Therefore, Leal (2005) in the book entitled The Autonomy of the Research Subject and Research Methodology, refers to this type of triangulation in this way:
He calls it methods and techniques and states that it has to do with the multiple use of methods to study a specific problem. "For example, when the interview technique is used as an initial process of gathering information and then being contrasted with the participant observation and/or group discussion."
It is a type of opposition of data from subjects of diverse grouping natures, for example, itself, a family group, a community, a couple ... etc.
Ruth and Finol (2009) point out that the researcher can collect data from individuals, couples or groups, or each of the three types. Data collection from one source is used to validate the data from the other sources or only one. Each level of data is used to validate the findings of the other level.
Also the triangulation of people, Researchers are subjects specialized in the analysis of a phenomenon. This group may have differences in its composition and its way of relating to the object of study. Their years of training and type of training do not have to be the same.
Leal (2005)… “based on the principle of complementarity, it is possible to compare or triangulate the results of qualitative and quantitative research to have a closer view of reality”.
Triangulation and it proccess
Finally, this author points out that each triangulation has a structural process. That is, a kind of scheme for its development that in each case is given thanks to another important point. They can be categories, which originate from the data, characterize the study phenomenon and guide these oppositions or contrasts.
