1.9.1 Normality Test

The researcher use normal test to treatment the data. This test is used to Measure whether the data are normally distributed or not. The criteria of normal distributions are: Ho: The distribution of the data is normal Ha: The distribution of the data is not normal The Hypothesis is accepted if the result of the normality test is higher than 0.05 sig α. In this case the researcher used the One Sample – Kolmogorov – Smirnov Test SPSS to test the normality test.

3.10. Hypothesis Testing

The hypothesis testing was used to prove whether the hypothesis proposed in this research was accepted or not. SPSS was used to know the improvement of treatment effect. The hypothesis is analyzed at significance level of 0.05 in which the hypothesis is approved if Sig α. It means that probability of error in hypothesis is only about 5. After collecting the data, the researcher recorded and analyzed them in order to find out whether there was an increasing in students’ ability in writing or not after the treatment. The researcher used Paired Sample T-test to know the level of significance of the treatment effect. 40 The formulation is: And ∑x 2 d = ∑d 2 – Md = mean from the differences pretest and posttest posttest-pretest Xd = deviation of each subject d – md ∑x 2 d = total of quadratic deviation N = subjects on sample Arikunto, 2010: 349-350 The criteria are: H : There is no improvement of the students’ narrative writing ability after being taught by using animation film. The criteria is Ho null hypothesis is accepted if alpha level is higher than 0.05 α 0.05 H 1 : There is an improvement of the students’ narrative writing ability after being taught by using animation film.
