The Technique of Data Collecting

1 From the menu at the top of the screen click on Analyze then Compare Means then One-Way ANOVA 2 Move the data from experimental class into the Dependent list and the data from control class into the Factor 3 Under Contrast and Post-Hoc ensure that there is a tick next to Options. 4 Click on the Options tab to open the options dialogue box. 5 Place a tick in Homogeneity of variance tests. 6 Click Continue, and then OK. 12 c Specification of Interview After conducting the research and getting the result. The writer does the interview to the selected students from the technique of simple random sampling. This interview questions are related to what question that is needed to be asked, how to arrange the question, how long the interview will be done, and how to formulate the questions. 13 Moreover, Patton explains the six kinds of question that can be an orientation in formulating the interview questions as follows: 1. The question which is related to the experience 2. The question which is related to the opinion or value 3. The question which is related to the feeling 4. The question about knowledge 5. The question which is related to the sensory perception 6. The question which is related to background or demography 14

G. Hypothesis Test

For hypothesis test, the writer uses t-test to find out whether there is significant difference between experimental class and control class in this study. 12 Budi Susetyo, op. cit., pp. 71-72 13 Lexy J. Moleong, Metodologi Penelitian Kualitatif, Bandung: PT. Remaja Rosdakarya, 2001, p. 140 14 Ibid., pp. 140-141 The writer uses t-test which is adapted by Anas Sudijono to find the result. There are several steps before applying the t-test formula. 15 The formula of t-test which is used in this research is: Note: t0 = The value of ‘t’ count M = Mean variable of experimental class M2 = Mean variable of controlled class SEM 1 = Standard Error of experimental class SEM 2 = Standard Error of controlled class The procedures of calculation are as follows: 1. Determining Mean of Variable X ∑ 2. Determining Mean of Variable Y ∑ 3. Determining Deviation Standard of Score of Variable X √ ∑ 4. Determining Deviation Standard of Score of Variable Y √ ∑ 5. Determining Standard Error of Mean of Variable X √ 15 Anas Sudijono, Pengantar Statistik Pendidikan, Jakarta: PT Raja Grafindo Persada, 2004, pp. 314-316.
