University considering that they can be generated as non-English students major. Moreover, completed four levels of General English for four semesters and finally
attended the ESP especially Medical English for Medical students and Law English for Law students, both groups were considered to master the same level of English
proficiency. Accordingly, Medical and Law students were in Intermediate level, hence, had developed their English skill to cope with the higher level of English
which was English based on their specializations or fields. However, all classes have the same chance to be observed, therefore here
the researcher applied random sampling in collecting the data. Type of random sampling applied in this study was simple random sampling. Randolph and Myers
2013:51 infer “random sampling refers to sampling technique in which each element of the population has a known and equal chance of being selected”. In other
words, a simple random sampling gives each member of the population an equal chance to be chosen. Constructively, Gorard 2004:67 contends that random
sampling has two keys advantages, namely: it is free of the systematic bias that might stem from choices made by the researcher, and, it enables the analyst to
estimate the probability of any finding actually occurring solely by chance. To know whether the different background of study fields affect the strategies and
modifications employed by the non-English students, here the writer designed Discourse Completion Tasks for various situational contexts for two different
groups, the Medicine group and the Law group. It is obvious that in deciding the number of the participants or the
respondents of each groups in a quantitative study, there is also a determination. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

The sample taken for the research has to fulfill requirement of the basic standard to make the study become valid. Gorard 2004:62 mentions that the number of sample
of respondents have to meet 30 to fully complete the responses of the analysis. This number is the good number for a correlational study where in this study the
researcher focused on finding the relation of difference between the two groups. In fact, one English class in Batam University had not more than 20 students,
hence, the researcher took two classes for each field of study using random sampling method. As a result, there were four classes assessed in this research. After
distributed the research instruments, the researcher found that there were students who did not attend the class at the day the research was conducted, and, on the other
hand, there were students who had no complete responses on 9 situations provided in DCTs. Since this research took only 30 students for each study field or faculty,
the researcher only selected the complete ones. In turns, the researcher had 60 samples from the total DCTs distributed with complete answers and responses to
avoid missing data used for t-test, afterwards, the t-test procedure could be conducted. These DCTs were divided into two groups: 30 DCTs of Medicine
students and 30 DCTs of Law students. This research is a single-moment study wherein the researcher emphasized merely on finding the difference between
Medical and Law students, but not about the development of their request strategies that signified the progress of their pragmatic competence. Finally, the details of the
data gathering conducted by the researcher are explained below. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
