Method of Data Analysis

respondents’achievement in acquiring English language. In order to show the relationship, the following have to be worked out:- The performance of the experimental group after being exposed to cooperative learning The performance of the experimental group after being exposed to cooperative learning strategies had to be analyzed using their pre test and post test results. The pre and post test results of the experimental group are shown in Table 4.1.

Deviation 21.017 13.342 7.675 As shown in Table 4.1, 93.8 of the subjects or 30 respondents showed positive score difference or improvement after they were exposed to cooperative learning method in the teaching of literature among the 32 subjects. Only 6.25 of the subjects or two respondents showed negative score after the treatment. The table also clearly showed the mean and standard deviation scores after the treatment in the experimental group. The mean score for pre test among the treated samples was 57.97 compared to the mean score of 82.42 in the post test. The post test showed an increase of 24.44 in the mean score among the samples in the experimental group. This finding was consistent with the finding of Janina 2003 that showed significant difference scores between the pre and post tests for experimental group. It showed that Cooperative learning resulted in higher achievement and greater productivity. Paired Sample T- Test Scores of Pre and Post tests for the Experimental Group Table 4.2 shows the paired sample T-test score of Pre and post tests for the experimental group.
