Intelligence Quotient IQ Data Description

Table 4.2 Classification of Intelligence Quotient IQ Classification IQ Near genius or genius 140 and above Very superior 130 – 139 Superior 120 – 129 Above average 110 – 119 Normal or average 90 – 109 Below average 80 – 89 Dull or borderline 70 – 79 Feeble-minded: moron 50 – 69 Imbecile, idiot 49 and below Adopted from Standford-Binet theory To provide an additional vivid description of the data distribution of IQ, the histogram of frequency distribution is presented in figure 4.1 as follows: Figure 4.1 The Histogram of Data of Intelligence Quotient IQ From the figure 4.1 above, the total number of students are 45 students. The students who got score 81 and 91 are 1 student for each, students who got score 100 and 106 score are 3 students, score 109 are 7 students, score 113 are 9 students, score 116 are 8 students, score 119 are 4 students, score 121 are 6 students, score 131 are 2 students and score 133 is 1 students. Apparently, from the symmetrical bell-shaped curve, it shows that the data of IQ is normally distributed. Intelligence Quotient IQ Intelligence Quotient IQ Then, to count the statistics score of IQ, the writer used SPSS program in the 24.0 version. The purpose of counting the statistics score is to know the mean, median, mode, maximum and minimum score, and sum. The data is described as follows: Table 4.3 The Statistics Score of Intelligence Quotient IQ From the descriptive statistics above, the respondents of this study is 45 students. The mean of IQ score is 133.22, which means that it is the average students could be classified as above average IQ. The median score of IQ is 113.00. Then, the mode of score is 113, which means that most students have 113 score in IQ test. The lowest score of IQ is 81 while the highest is 133, so the range score is 52. In addition, the standard deviation score is 9.349 and the variance is 89.086. Based on description above, it can be concluded that the seventh semester students of Department of English Education have the high average IQ score. It can be seen that most of students obtained score 113, in which score 113 is classified as high average IQ. Overall, they can be said as smart students.

2. Students’ Achievement of Extensive Reading

As Y variable dependent va riable, students’ achievement of Extensive Reading was taken from documentation of Extensive Reading score list from the lecturer of Extensive Reading course. The description is shown in table 4.1. Table 4.4 The Scores of Extensive Reading Students’ Number Extensive Reading Score Y Student 1 83 Student 2 76 Student 3 81 Student 4 84 Student 5 76 Student 6 87 Student 7 81 Student 8 14 Student 9 81 Student 10 76 Student 11 85 Student 12 80 Student 13 87 Student 14 85 Student 15 89 Student 16 73 Student 17 87 Student 18 85 Student 19 77 Student 20 84 Student 21 90 Student 22 71 Student 23 85 Students’ Number Extensive Reading Score Y Student 24 86 Student 25 85 Student 26 84 Student 27 85 Student 28 70 Student 29 80 Student 30 80 Student 31 72 Student 32 75 Student 33 88 Student 34 81 Student 35 81 Student 36 85 Student 36 84 Student 38 85 Student 39 88 Student 40 85 Student 41 85 Student 42 77 Student 43 86 Student 44 84 Student 45 85 To provide an additional vivid description of the data distribution of Extensive Reading achievement, the histogram of frequency distribution is presented in figure 4.1 as follows: Figure 4.2 The Histogram of Data of Extensive Reading Achievement From the figure 4.2 above, the total number of students is 45 students. The students who got score 14, 70, 71, 72, 73 and 75 are one student for each, students who got score 76 score are 3 students, score 77 are 2 students, score 80 are 3 students, score 81 are 5 students, score 83 are 1 students, score 84 are 5 students, score 85 are 11 students, score 86 are 2 students, score 87 are 3 students, score 88 are 2 students and score 89 and 90 are one students for each.
