Level of Difficulty Try out Test

questionnaire was another resource besides the teacher observation to find out the students’ problem in teaching through PPP technique. 8. Administering the post test The students had their time to do the post test after the treatments had been finished. The post test items were the same as the pre test items which consist of 30 item test of compound sentences. The researcher took about 45 minutes for students finishing the post test 9. Analyzing the data The next step was analyzing the data have been collected. The data analysis used the data from the pre test and the post test result. Both of the data were compared in order to know whether there was a significant increasing in students’ score after receiving the treatment by using PPP technique. 10. Reporting the result The data had been analyzed reported in the researcher ’s paper systematically start from the data from the pre test and followed by the data from the post test. In the paper, the researcher knew the answer of his first research problem that was to know whether the PPP technique can give students significant increasing of a mastering the compound sentences.

3.7 Data Analysis

The next step of this research was analyzing the data. Analyzing the data was administered to give the researcher a proof whether there was a significant increase of students ’ mastery of compound sentences through PPP technique at the second grade students of SMA Xaverius 1 Belitang. In analyzing the data, the researcher did some steps below: 1. Calculating the score from the pre test and the post test. 2. Tabulating the result of each test and measuring the mean of each test result. In order to get the mean or the average score of each test, the researcher applied the following formula: M = ∑ � Where: M : Mean Average score ∑x : Total students’ score N : Total number of students The average score of test was the result of total students’ score divided by the total number of students. Hatch and Farhady, 1982: 55 3. Making a conclusion from the tabulated result of the pre test and the post test which had been delivered. The researcher analyzed the data had been collected by applying the statistical computerization Repeated Measures t-test of SPSS 15 for Windows i.e. t = 1 − 2 � to test whether there was a significant difference between pretest and the post test or not, in which the significance was determined by p 0.05 Hatch and Farhady, 1982:114. Whereas: � = � � SD = ∑ � 2 − 1 �−∑ � 2 �−1
