four students included in this group. In the post-test data, we can find twenty two students are considered having average ability in pronunciation. However, only
nineteen students are considered in this level when the pre-test done. The last is good ability level. In the good ability level, there are two
students included in this level in the pre-test. Nevertheless, in the post-test we can find there are five students considered having good pronunciation ability.

of the pre-test are varied from 55 to 87.

From the table above, we can see there are seven students that are included into poor ability students. Meanwhile from the pre-test score, there are only five
73 students included in this group. For average ability, there are fifteen students from
post-test and there are eighteen students from pre-test. The last is good ability level. In this level, there are eight students from the post-test and seven students
from pre-test. Based on the explanation above, it implies that there is improvement of
students‟ pronunciation ability in general after getting treatment using Fidel Charts as the media.
4.5.2.4 Overall Post-test Analysis
In this part, the post-test score of the experimental and control groups will be compared in one chart. Chart. 4.2 below shows the score got by each group in the
post-test after getting treatments.

74 improved from average ability became good ability. Meanwhile the two control
groups‟ are still in the average ability. ɑlthough the two groups‟ mean score improved.
To prove that there is significant improvement of the experimental and control groups. T-test and Wilcoxon-Signed Ranks Test should be done. T-test
should be done to Experimental Groups and the Fidel Charts group. Meanwhile the Songs Group should be tested using Wilcoxon-Signed Ranks Test because the
number of the students of Songs group consists of less than thirty students.
