Telephone enquiries (CATI)
Hopp & Partner have 20 CATI-terminals at their disposal and is therefore able to also conduct more extensive population enquiries in real-time. Our studio is equipped with modern CATI-software and allows listening-in on interviews internally or externally through live-streaming. We use the contemporary VoIP- telephony and this way are able to offer national and international enquiries cost-efficiently.
We carry out computer assisted telephone interviews (CATI) either in only limited regions or nationalwide or internationally. A telephone enquiry can also be based on an existing customers´ data set, an acquired address data stock, or as a representative survey.
Our pool of multilingual interviewer (native speakers) conduct interviews in many languages such as English, French, Spanish, Italian, Polish, or Russian. This way, for instance, a parallel Europe-wide enquiry of one target group is possible.
Representative population surveys
For representative population surveys Hopp & Partner employs by request the Gabler-Häder-sampling procedure (Gabler-Häder-Stichprobenverfahren) in order to also consider those telephone numbers not listed in telephone registers and to achieve a genuine random sample. (The Gabler-Häder-method is also used for creating an ADM-master sample).
Enquiries can be focused on the total population or merely on special target groups (e.g. persons interested in travelling, drivers, persons with higher income etc.).
Omnibus surveys
The Berlin population is your target market? Hopp & Partner conducts the Berlin omnibus „Source market Berlin“ („Quellmarkt Berlin“) twice per year, where you can save costs by including simple single questions. This way micro-surveys with two questions including socio-demographics are already possible from 1.000 €. Deadline is March 1st, respectively September 1st.
