CHAPTER III RESEARCH METHOD
A. Research Type
According to Vanderstoep and Johnston 2009:310 narrative and textual description  of  the  phenomena  under  study  is  produced  by  qualitative  research.
They  also  add  that  the  purpose  of  qualitative  research  is  more  descriptive  than predictive since the goal of qualitative research is to understand the point of view
of  research  participant  deeply  Vanderstoep  and  Johnston,  2009:167.  By  this regard, the qualitative method was applied in this research as the purpose of this
research was to describe as well as to understand the findings of the phenomena of politeness  features  of  criticism  deeply.  Furthermore,  this  research  was  also
supported  by  quantitative  data  in  which  the  researcher  used  numbers  and frequency of the data occurrences in order to deepen the qualitative interpretation.
As  stated  by  Creswell  2009:204-205,  by  incorporating  both  qualitative  and quantitative  approach,  it  can  broaden  understanding  of  the  research  problems.
Therefore, by employing quantitative data as a supporting element, the researcher can gain a better understanding of the findings of the research.
