3.5 Data Analysis Technique
The data of the research were numeric and word data. They were taken from the treatments, which were given by the researcher. This treatment was
aimed to solve students’ difficulty in English vocabulary learning in OI 703 Petra Children Development Center. Treatment provided the result, which was required
for data analysis. This research chose weekly journal and weekly quizzes as the data gathering techniques to observe the improvement of students’ retention in
their vocabulary learning. Accordingly, the results of weekly observation and quiz were the result of the research. They measured progress of students’ retention in
their English vocabulary learning. In order to be able to observe the progress of the students, the researcher
set up standard of the amount of the vocabulary items. The standard was thirteen English words out of fifteen English words, which were used in the English
vocabulary learning. From the standard amount of the vocabulary which was used, the researcher was able to measure students’ vocabulary retention from their
weekly quizzes scores. The calculation of the numeric data used the following formula:
Note: Mn : Mean an indicator of central tendency of the sources set
The Mean was counted using the formulation below: _
Mn = X = S X N
_ Note: X
: the range point S X
: the sum of all score N
: the number of samples PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
As professional, the researcher expected the result of data which could influence decisions on teaching and learning to be both valid and reliable.
Therefore, the researcher also used a data gathering technique, it was a weekly journal to collect the word data. Sagor 2005: 93 stated the strategy used most
frequently by action researchers was called Triangulation Matrix. Table 3.1 was the example of Triangulation Matrix which was used by the researcher:
Table 3.1 Triangulation Matrix: Three ACR Questions Sagor, 2005: 96
Research Question Data source 1
Data source 2 Data source 3
What did I actually do?
What changes occurred with our
priority achievement
targets?
What was the relationship
between the actions taken and changes
in performance on the achievement
targets?
The table was adopted from Sagor 2005: 96 in his book entitled The Action Research Guide Book.
The Triangulation Matrix was designed to recount word data which occurred in the teaching and learning of vocabulary. It was in the
form of journal thus it only recorded word data. PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
