Statement of intent

3. The Moderator variable is a special variable which may impact the relationship between the dependent and independent variables. To distinguish, factors such as students’ age, gender, social position, background knowledge, current language proficiency can be regarded as the moderator variable which may influence the correlation between the task of the experiment and goal of the experiment. During the research investigator faced some obstacles which may be moderator variables such as: almost all the students had different background knowledge, acquisition and language level which created some challenges for the researcher to carry out the experiment. Contrastingly, few students had quite confident knowledge of English language that again caused a difficulty for the researcher to control them in order those intelligent students to give chances to other ones to produce the language and involve the task of the research. It includes the factors that influenced the relationship between the subjects’ proficiency in English and the relationship of male and female subjects in role plays.
