RE: Blockchain Global Expo 2018 - day 2
Excellent walkthrough for those of us that didn't attend. I am confused about the corruption perception index chart. The score. New Zealand scored 89 in 2017. Does that mean they were the least corrupt out of 89 total countries? Because I see 90 and 91 for previous years. Are there two fewer countries this year?
Thank you.
No, "89" is a synthetic score, it doesn't represent the number of coutries that were ranked (I think more than 180 countries were ranked). I suppose it's constructed by asking people to fill a questionaire containing questions such as "on a scale from 1 to 10, with 1= 'totally corrupt' and 10='not currupt at all', how would you mark the corruption level in public procurement".
Then an average mark is calculated over several such questions.
