Data Collection

We use all modern data collection methods.

Ipsos Tambor utilizes all modern data collection methods, which enable fast processing of research data.

Data collection is a standardized process with detailed control mechanisms, which guarantee the high quality of data collection.

The swift completion of projects is usually achieved by the involvement of a sufficient number of interviewers in the research project, the rapid performance of preparation work(creation of the questionnaire / scenario, recruitment of respondents and research project organization), and the quick completion of research project evaluation work(controls, data entry, data analysis, final report, etc.).

Ipsos Tambor strives on a continuous basis to improve its work methods and optimize all its operations to be as fast and effective as possible.

RESPONDENT SELECTION METHODS:

• Probability
• Quotas (systematic, stratified, regional)
• Use of the databases of companies and physical persons

The selection method is always fully subject to the needs of the research project so that the target group of the client is reached.

Quota selection is the most frequently used method. The following criteria are standardly used for the selection of respondents:

• Region
• Size of town/city of residence
• Age
• Education
• Sex

Our selection of respondents is based on current information supplied by the statistical office of the specific country. Therefore, results are representative for the entire population or selected segment of the population (target group).

WE OBSERVE THE FOLLOWING RESPONDENT SELECTION RULES:

• Respondents must strictly meet all selection quotas.
• Repeated participation of respondents in research is monitored and limited.
• Relatives of the interviewer may not participate in research.
• Only one person per household may participate in research.
• Respondents may be neither employees of the company commissioning the research, nor employees of its competitors.
• Respondents may participate in a given research project only once every six months.
• Respondents may participate in research on the same product only once every two years.
• Every respondent is entered into the company database and if it is determined that he/she has participated in previous research projects and does not meet the above-mentioned criteria, he/she is excluded from the research.
• All recruitment criteria are exactly specified before the start of research and approved by the client.
