3.4.3.1 Calculating the Likert Scale

To follow Ockert 2005, two answers see appendix C gained from the questionnaire were calculated using Likert scale; the steps were scoring, finding out the score of the answer, calculating the central tendency of the answers, and classifying the average percentage. Those steps are considered to be processed in order to make the statistical number Ockert, 2005. The steps are pointed out as follows. a Scoring Each answers were labeled with value from 1-4. Example of scoring students’ answers in the positively-framed statements is depicted below. Table 3.2 Likert-Scale statements scoring rubric Category of Response Strongly Disagree Agree Uncertain Disagree Strongly Agree Score 1 2 3 4 5 Table 3.3 Example of Statement in this research No Pertanyaan Tidak sama sekali Sedikit Ragu- Ragu Kadang- Kadang Sangat Suka 1 2 3 4 5 2.

The classification is based on the criteria above. Table 3.5 Score of percentage and its interpretation Score of Percentage Interpretation 00 - 20 Very Weak 21 - 40 Weak 41 - 60 Enough 61 - 80 Strong 81 - 100 Very strong Taken from Akdon 2008 According to Ockert 2004, the interpretations of score percentage were made to make the descriptions of the data more systematical. Moreover, the interpretation which based on score percentage was formulated in order to classify the tendency of the response.
