E. Data Analysis
When data were collected, the researcher made the data analysis, in order to check on working hypotheses and the results. It dealt with the materials
providing systemic observation of the research. Bogdan and Biklen 1982:145 explain that in qualitative data analysis, the researcher has to do several steps,
they are working with data, organizing it, breaking it into manageable unit, coding, and deciding what the data is being analyzed. This standpoint is also
supported by Wiersma and Jurs 2009:239 who state that there are three processes in doing data analysis, such as categorization, coding and description.
In other words, the data analysis requires organization of the data which are being studied.
The researcher read the script in Canvas and made the notes relating to the phenomenon of schizophrenia in terms of language and behaviour of a
schizophrenic character in Canvas. Then, the data was categorized which included in the kinds of speech abnormalities and behaviours. Therefore, the data consist of
two categories. They are the kind of speech abnormalities and accompanying behaviour of a schizophrenic.
F. Trustworthiness
A good research must provide valuable data describing the phenomenon well. The validity information may give an indication how reliable the research
itself. To obtain the validation, this research uses triangulation as a means of verifying many elements which assumes the reality deeply. In fact, the
triangulation represents varieties of data, methods, and theories.
Denzin in Berg 2001:5 outlines these four categories included in triangulation:
1 Data triangulation has three suttypes: a time, b space, and c person. Person analysis, in turn, has three levels: a aggregate, b interactive, and c
collectivity.2 Investigator triangulation consists of using multiple rather than single observers of the same objects. 3 Theory triangulation consists of
using multiple rather than simple perspectives in relation to the same set of objects.4Methodological triangulation can entail within-method
triangulation and between-method triangulation
In this case, the researcher applied two kinds of triangulations. They were investigator and theory of triangulation. The investigator triangulation is
characterized by the different observers or interviewers making balance out the subjective‘s influences to individuals. Thus, the researcher asked her thesis
advisors, Titik Sudartinah, M.A., and Nandy Intan Kurnia, M.Hum., to make this research credible. Additionally, the researcher made peer review with the students
who were majoring in linguistics. They were Fitria Nur Kiswandari, Kristiana Tri Wahyuni, and Maya Permata Sari to strengthen the validity of the data of the
research. Meanwhile, the theory triangulation was checked by observing the data and the theories used in this research.
