2.15 Hypothesis
Before the researcher presented forward the hypotheses, she would like to give an
explanation about what a hypothesis was. A hypothesis is a tentative statement about how to deal with the defined problems Bernard Philips 1974 in B. Dubey
2008. Using a hypothesis enabled the writer to focus her work so she could gather the data she needed in order to come to some conclusions.
Based on the frame of theory and theoretical assumption above, the researcher
formulated the hypothesis. These hypotheses were used to prove whether the hypotheses propose in this research is accepted or not. The researcher used SPSS
Independent T-test. The hypothesis would be analyzed at the significant level of 0.05 in which the hypotheses were
approved if sign α. T means that the probability of error in the hypotheses are only about 5.
The hypotheses were:
1. There is significant difference of vocabulary achievement between the
students who are taught through logico and those who are taught through crossword puzzle.
2. Logico is more effective than crossword puzzle for teaching vocabulary.

CHAPTER III RESEARCH METHOD
1.1
Research Design
The research was a quantitative research. Hatch and Farhady 1982 stated that quantitative is kind of research in which the data used tend to use statistics as
measurement in deciding the conclusion. In this research, the researcher used pretest posttest control group design which belongs to the true experimental
designs. There are three basic characteristics of true experimental designs into three:
a. A control group is present.
b. The students are randomly select and assigned to the groups.
c. A pretest is administered to capture the initial differences between
the two groups. Hatch and Farhady 1982:22
These three characteristics allow us to avoid almost all the problems associated with external and internal validity.
They said that this design deals with two groups; both of the two groups receive
the treatments, experimental class receive treatment through logico and control class as comparison receive treatment through crossword puzzle.
