The Population and Sample

Table 3.4 The Questionnaire scoring Scale Affirmative Statement Score Negative Statement Score Strongly Agree 5 1 Agree 4 2 Neutral 3 3 Disagree 2 4 Strongly Agree 1 5 The questionnaire was translated into Bahasa Indonesia which was aimed to avoid the possibility of different perception in understanding the statement. Therefore, using Bahasa Indonesia in the statement was useful for students to understand and answer the question. To obtain the data from the respondents, the researcher made try out the questionnaire to determine the validity and reliability. The writer got the standard coefficient validity minimun for this instrument with N= 25 and coefficient validity is 0.3 to see the validity of instrument, the researcher used SPSS 22 to measure the validity and realibility of questionnaire. Based on the try out result of the quetionnaire validity of the 40 items, it showed that 31 items were valid. The number of invalid item were 2, 10, 14, 24, 25, 26, 35, 36, 40. . Table 3.5 Cronbach Alfa Table Reliability Statistics Cronbachs Alpha N of Items ,813 40 From the table above, it can be seen that the value of cronbach’s alpha is 0.813. That meant that the questionnaire was reliable because the score was bigger than 0.60.

2. Test
