3.3.1  Independent Variable
Independent variable is a variable that makes change in the value of one variable. In this  research,  the  independent  variable  is  using  tea  party  as  the  technique  to  teach
conditional sentences.
3.3.2  Dependent Variable
The dependent variable is the variable that the researcher observes and measures to determine  the  effect  of  the  independent  variable  that  is  measured  in  order  to  know
how far the independent variable affects it. The dependent variable of this research is
the effectiveness in teaching conditional sentences. 3.4
Method of Collecting Data
The method of collecting data should be applied in conducting the research in order to get the appropriate result of the research.
3.4.1 Type of Data
The  data  for  the  objective  of  this  research  were  students‟  scores  in  mastering conditional  sentences  after  they  were  taught  by  using  tea  party  technique  for  the
experimental group and using traditional technique for the control group.
3.4.2 Instrument for Collecting Data
Instrument  is  an  important  device  to  collect  data  in  a  research  program.  In  this research,  a  test  was  used  as  a  method  of  collecting  data.  In  general,  there  are  two
kinds of test namely essay test and objective test. However, I used the objective test,
and  it  was  multiple  choice  test  and  fill-in-the-blank  test.  These  types  of  tests  were chosen because of some advantages. Those were: the technique of scoring was easy;
it would be easy to compute and determine the reliability of the test; and it would be more practical for the students to answer.
3.4.3 Try-out
Try-out  test  is  highly  important  since  the  result  will  be  used  to  make  sure  that  the instrument has such characteristics as valid and reliable. The try-out test consists of
40  items.  After  scoring  the  result  of  the  try-out,  I  made  an  analysis  to  find  the reliability, validity, level of difficulty, and discriminating power of the items on the
multiple  choice  test.  Then,  for  fill-in-the-blank  test,  I  assigned  three  validators  to check the validity.  All  the items  were used to  decide which item  should be used in
making instrument.
