F. Data Analysis Techniques 1. The First Questionnaire Needs Analysis

The data collected from the first questionnaire Needs Analysis were analyzed through calculating the percentage of each answer of the questionnaire by using the formula of: 41 P : Percentage f : Frequency N : Total of Respondents 100 : Fixed Number

2. The Second Questionnaire Expe rt Judgment

The second questionnaire Expert Judgment uses Likert-Scale as the instrument of measurement. Previously, the data were calculated by calculating the means of the data. The means were calculated by using the formula of data conversion below. Mn X ¯ = ∑fX N Mn X ¯ : Mean ∑fX : The Sum of Scores N : The Number of Questions Then, the means were converted to the descriptive analysis which is derived from the formula proposed by Suharto 2006: 52-53. The formula is presented below. R : Range Xh : The Highest Score Xl : The Lowest Score 4 : Range of Likert-Scale R = �ℎ−�� 4 P = � N x 100
