5. analyzing the data accurately by grouping the data into their own types and transferring them into tables 6. reporting the result of the data after the data were classified and analyzed There is one data sheet in this research. It consists of types of turn-taking irregularities and type of reasons for turn-taking irregularities in the conversations among the characters in the movie.

G. Trustworthiness of the Data

Trustworthiness is very important to prove whether the result of the study is valid or not. Moleong 2006:326 states that there are four criteria as the basis to gain trustworthiness. Those are credibility, transferability, dependability, and comformability. To achieve the trustworthiness of qualitative research, this research principally applied credibility and conformability criteria. Credibility refers to the richness of the information gathered and on the analytical abilities of the researcher. Conformability, in turn, aimed at measuring how far the researcher analyzed the neutrality of cases. The findings and the interpretation of the data should be truly based on the data. In achieving credibility and conformability the researcher used triangulation techniques. Triangulation is a technique for checking the trustworthiness of data by utilizing something outside the data to verify the data or to compare them Moleong, 2001:128. To achieve the credibility of the data, the researcher consulted the findings to her consultants from the beginning until the end of the research process. In addition, peer discussion was conducted to check the data analysis. The researcher discussed the data with her colleagues from English Department who are majoring Linguistics to do the validation of the data.
