D. Data Description

To know the result of the test, the writer makes the table of student’s score for each class as follows: Table 4.1 The Test Scores of the Experimental Class Students Student Score Student Score Student Score 1 80 16 80 31 92 2 66 17 88 32 92 3 70 18 84 33 84 4 54 19 60 34 84 5 84 20 92 35 72 6 76 21 96 36 80 7 72 22 88 37 92 8 84 23 88 38 88 9 80 24 84 39 84 10 56 25 84 40 88 11 80 26 72 41 92 12 84 27 84 42 72 13 84 28 84 43 84 14 88 29 80 44 80 15 88 30 80 45 82 Score f 92 – 96 87 – 91 82 – 86 77 – 81 72 – 76 67 – 71 62 – 66 57 – 61 52 - 56 6 7 14 8 5 2 1 2 45 = N 1 33 Table 4.2 The Test Scores of the Controlled Class Students Student Score Student Score Student Score 1 60 16 80 31 88 2 52 17 78 32 88 3 70 18 78 33 80 4 68 19 66 34 80 5 76 20 84 35 80 6 74 21 88 36 74 7 82 22 76 37 80 8 76 23 84 38 72 9 76 24 74 39 80 10 76 25 88 40 86 11 88 26 80 41 80 12 88 27 84 42 80 13 84 28 76 43 80 14 84 29 72 44 80 15 80 30 84 Score f 92 – 96 87 – 91 82 – 86 77 – 81 72 – 76 67 – 71 62 – 66 57 – 61 52 - 56 6 8 14 11 2 1 1 1 44 = N 2 Table 4.3 The Result Calculation of Experimental Class Score f X x’ x’ 2 fx’ fx’ 2 92 – 96 6 + 2 4 + 12 24 87 – 91 7 + 1 1 + 7 7 82 – 86 14 M’ 84 77 – 81 8 - 1 1 - 8 8 72 – 76 5 - 2 4 - 10 20 67 – 71 2 - 3 9 - 6 18 62 – 66 - 4 16 57 – 61 1 - 5 25 - 5 25 52 - 56 2 - 6 36 - 12 72 45 = N - - - - 22 = ∑ fx’ 174 = ∑ fx’ 2 Table 4.4 The Result Calculation of Controlled Class Score f Y y’ y’ 2 fy’ fy’ 2 92 – 96 + 3 9 87 – 91 6 + 2 4 + 12 24 82 – 86 8 + 1 1 + 8 8 77 – 81 14 M’ 79 72 – 76 11 - 1 1 - 11 11 67 – 71 2 - 2 4 - 4 8 62 – 66 1 - 3 9 - 3 9 57 – 61 1 - 4 16 - 4 16 52 - 56 1 - 5 25 - 5 25 44 = N - - - - 7 = ∑ fy’ 101 = ∑ fy’ 2 1.
