CHAPTER III RESEARCH METHODOLOGY
This chapter presents the research design, the place and time of the study, the population and sample, the research instrument, the technique of data
collecting, the technique of data analysis, and statistic hypothesis.
A. The Research Design
The research design of this study is quasi-experimental study, using comparison or control group to investigate research question without random
assignment
1
, which aims to know whether English songs from YouTube is effective towards students’ vocabulary mastery. The quasi-experimental design
describes in the following table:

Table 3.1 Pre- and Post-test Design
Select Control Group Pre-test
No Treatment Post-test
Select Experimental Group
Pre-test Experimental
Treatment Post-test
Based on the table above, the writer takes two classes, the experiment class and control class. Before giving treatment, the writer gives pre-test to both of
classes. Then the writer teaches the students in experimental class by using English songs from YouTube and in controlled class without using English songs
from YouTube. After four meetings, the writer gives the post-test to the both classes. It is given to know the effectiveness of English songs from YouTube
