b. choose compare means c. choose one way anova
d. fill dependent list column and factor column e. choose option
f. mark on descriptive and homogeneity of variance test g. choose OK
Then, the result of testing data homogeneity was as following:
Table 4.3
The data was categorized as homogeneous data if the significant value was more than 0.05 and the F-value was less than the F-table. In this research, from the
table above, the significant value was 0.773 and the F-value was 0.667. This data was categorized as homogeneous data because the significant value was more than
0.05 and the F-value was less than the F-table, 2.27. 3. Test of Data Linearity
The data in this research was linearity tested in order to know whether the data were linearly correlated or not. The researcher used SPPS Statistical Product and
Service Solution in calculating the data linearity by following these steps: a. choose analyze
b. choose compare means c. choose means
d. choose dependent and independent variable e. choose option
f. on statistic for first layer, choose test for linearity

The result of data linearity was as following:
Table 4.4 ANOVA Table of linearity Test
The linearity of data could be seen from a linearity significant value. If the linearity significant value was above 0,05, the data was concluded as linear data.
From the table above, the value of linearity significant value was 0,654. Therefore, this data was categorized as linear data.
After testing those three tests- test of data normality, test of data homogeneity, and test of data linearity- the data in this research fulfilled the requirements of
parametric statistic. Hence, the researcher used parametric statistic in analyzing quantitative data.
c. Qualitative Data Description
In describing the qualitative data, the researcher elaborated the interview specifica
tions with the learners’ responses in a table as following:

penggunaan media gambar dalam belajar materi comparative adjectives?
5 of 6 learners stated that: - the use of pictures could create
interesting, unboring, fun, and enjoyable class.
- learners felt happy when learning comparative
adjectives by the use of pictures.
- pictures could make learning material easier and more
understandable. - the use of pictures affected on
their score. 1 of 6 learners states that:
- the use of pictures was time consuming and made the
learning material unclear. - the use of pictures did not
assist in memorizing learning material.
- the use of pictures did not effect on his score
2. Data Analysis
a. Quantitative Data Analysis and Hypotheses Testing
Analyzing quantitative data was conducted to answer the first research question about whether or not the use of pictures affected
the learners’ score when learning comparative adjectives. Because the data of this research fulfilled the requirements
of parametric statistic, the researcher used t- test formula in comparing means between two data groups, pre- test score and post- test score, for testing research
hypotheses. The researcher used SPSS Statistical Product and Service Solution in
analyzing the quantitative data. As the result of analyzing, the researcher provided it as follow:
Table 4.6
In testing the hypotheses, the hypotheses of this research are: H
: The use of pictures does not affect on learners’ score in learning
comparative adjectives significantly. H
₁: The use of pictures affects on learners’ score in learning comparative adjectives significantly.
Further, the criteria of testing hypotheses are: H
is accepted if t-value is less than t-table. H
is rejected if t-value is higher than t-table.
