Other resources
The institute annexes that accompany the publications and the sources the concepts and the method rest on are gathered in one place. Annexes are tied to the record of the publication concerned; the sources are common to the whole measurement round.
Institute annexes
-
Method annex. Every measurement is published with a method annex covering universe, sampling, questionnaire, weighting and uncertainty; a result without its annex is not published.
-
Glossary of terms. Perception, attitude, trust, experience, factual estimate and perception gap: the definitions of the measured concepts and their equivalents are kept in a single list, TR · EN · DE.
-
Aggregated data. The aggregated tables, the questionnaire and the data dictionary of every study are shared under an open licence (CC BY 4.0) with the first measurement round.
Sources
The sources on which the concept definitions and the measurement approach rest; a citation to the institute's own documents is not counted as sufficient on its own.
