A. Research Findings
1. Data Description
In describing data of this research, the researcher divides this part into two parts. Firstly, there is a description about quantitative data, and secondly, there is a
description about qualitative data. This part is divided into two parts because the researcher needs to analyze both quantitative and qualitative data to answer two
research questions. The quantitative data is needed to answer first research question about the effect of the use of pictures in learning comparative adjectives
to learners’ score. Moreover, the qualitative data is needed to analyze to answer second research question about the effect of the use of pictures in learning
comparative adjectives to learners’ perceptions. Besides, those two data description, there is also elaboration about assumption test of quantitative data.
a. Quantitative Data Description
As described in previous chapter, the researcher held the research at MTs. Al- Islamiyah Ciledug Tangerang. She held the research by taking the learners
