source of the data. The film is chosen since the characters employ many kinds of positive politeness strategy. Besides, the characters represent the people in real
life, the social and situational contexts are like in the characters in the real world. Data in this research contain the positive politeness strategy expression spoken by
the characters in the film entitled “In Good Company”.
G. Sample and Sampling Technique
Sample is part of the population investigated, while sampling is the activity of collecting the samples. Concerning with the nature of qualitative study,
the sampling technique adopted in this research is purposive sampling or criterion based on the purpose of the research Hadi:1983.
Meanwhile, Moleong 2001:165 states that sampling technique for a qualitative research is different from that of a quantitative one. Samples in a
qualitative research are related to the context, namely each datum is treated based on the context. He also clarifies that qualitative research does not explore random
xlix sampling but purposive sampling. Consequently, the choice of the technique is
appropriate to this research. In this purposive sampling technique, the selection of sample is from the
source of data having connection with the problem analyzed. The samples are chosen based on certain criteria set up by the researcher. The criteria of choosing
the samples are based on Brown and Levinson’s classification of positive politeness strategy. The samples of this research are the character’s dialogs that
employ positive politeness strategy in the film entitled “In Good Company”.
