Computing t obt and t crit to accept or or reject the null hypothesis: If the t obt t crit , or if degree of probability p 0,05 , the null hypothesis is not rejected, the two groups were homogenous.

3.15 Data Analysis on the Posttest Score

After the treatment was given to the experimental group and control group, post test scores of both classes are taken. The post test scores of each group were analyzed by using t-test for independent samples to find out significance difference between the two groups under comparison KranzlerMoursund, 1999. The analysis of the posttest score was done by taking the similar steps taken in the pretest score analysis. By the end of the calculation, t obt were gained and compared to t crit . If the t obt is equal to or greater than tcrit, the results are statistically significant. Then, the null hypothesis is rejected. In other words, there is a significant difference between the experimental group and control group. The calculation of both pretest scores and posttest scores were done with the assistance of Statistical Package for the Sosial Sciences SPSS 20 system. 68 Ratih Inaya, 2014 The implementation of audio storytelling technique in teaching listening comprehension Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu Then, the conclusion of this research will be based on those results of calculation. The findings and discussion of the data would be presented and discussed in chapter IV. 85 Ratih Inaya, 2014 The implementation of audio storytelling technique in teaching listening comprehension Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu

CHAPTER 5 CONCLUSIONS AND SUGGESTIONS

5.1 Conclusions

With regard to the finding of the study, the hypothesis of the study which targeted the effectiveness of using audio storytelling at a private University learners listening comprehension ability was rejected. The results of the t-test confirmed this analysis. The observed t value calculated by the SPSS was 2.00 while the critical value on the basis of two-tailed significance p-value 0.05 was determined 2.014 see table 4.4. According to the research question and hypothesis, the results of the study can be discussed, here, to clarify the difference between experimental group and control group performance after five meetings treatment. The results of the study say that there was a significant development in experimental groups listening comprehension ability using audio story task after the treatment sessions. This development can be defined because of the audio story as a complementary material to classroom activities. Designing stories to the educational space, as discussed earlier, are considered helpful. However, audio storytelling is strange a bit at initial step. That is, affecting factors can build obstacle and barriers to improving language learning and teaching procedure, especially listening skill. Yet benefiting from the native speakers performance stress, intonation, pitch, and rhythm is something. Therefore, the teacher actually tried to somehow consider subjects feelings and prepared them for the task. On the other hand, the control group
