What are the observed ranges of values that define tercile groups?

When grouping countries into tercile groups according to each indicator, the intention is not to suggest thresholds or target values for any indicator, but rather to allow a crude assessment of country’s performance relative to others. A country that is in the top group performs better than at least two thirds of countries (i.e., it is among the top third performers); a country that is in the middle group performs better than at least one third but worse than at least one third (i.e., it is among the medium third performers); and a country that is in the bottom third performs worse than at least two thirds of countries (i.e., it is among the bottom third performers). The observed ranges of values that define tercile groups for all indicators in dashboards 1-5 are given in Technical note 6 at http://hdr.undp.org/sites/default/files/hdr2018_technical_notes.pdf.
