There are different certificate levels of the ReDem® quality seal, depending on the type of survey, its size and the complexity of the questionnaire. In order to receive the ReDem® quality seal, the survey data for each certificate level must be subjected to a minimum level of quality control.
If a ReDem® quality seal is issued, it can also be found in the quality report. This report provides a comprehensive overview of the data quality and the quality controls performed. This ensures full transparency from data collection to quality control and data cleaning.
The quality seal, with a link to the quality report, can usually be found directly inside the study report or in an extra sheet in the survey data.
An individual ID is assigned to each seal. You can enter the ID here to check if it is valid.
