問卷內容是「在你的國家,司法系統面對來自政府、個人或企業的影響,獨立程度有多高?」,且依1-7分給分。(“In your country, how independent is the judicial system from influences of the government, individuals, or companies?” [1 = not independent at all; 7 = entirely independent] | 2017–2018 weighted average.)
而蒐集完問卷後有兩階段的排名分數製作,第一階段是將蒐集來的問卷依照歷年的彙總來作為權重(The computation of the score happens in two steps. In the first step we aggregate 2018’s answers and 2017’s answers using the sample sizes of each year as weights.)
第二階段是將該分數依照公式換算成無單位的0-100的分數,舉例來說,如果平均而言得到的分數是4分,那麼依照公式[(4-1)/(7-1)]*100,換算出分數為50。(In the second step, To allow the aggregation of indicators of different nature and magnitude, each indicator entering the GCI is converted into a unit-less score, called ‘progress score’, ranging from 0 to 100 using a min-max transformationFor example, if, on average, respondents assigned a score of “4” to the question above, this value is simply transformed into a 0-100 scale applying the formula (4-1)/(7-1)*100 = 50.)進而再依照該分數進行排名。
