Reliable figures?
But of course!

What is CATI? Telephone interviews during which responses are recorded with the aid of computers. CATI is used in bigger samples to quickly gather opinions.
Typical applications? Measuring awareness and advertising recall, tracking studies, opinion polls.
Limits to this method? Maximum interview length is 20 minutes; tends to exclude sets of explorative questions; socially desirable response behaviour can occur.
What is CAWI? Online-based interviews during which responses are directly recorded by the respondent on the internet. This method is used in bigger samples to quickly gather opinions.
Typical applications? Measuring awareness and advertising recall, tracking studies, pre-tests of print ads, TV and radio commercials.
Since January 2017 we have our own professional online-panel based on a cooperation with the institute Trend Research located in Hamburg. This partnership allows you direct access to a nationwide online-panel, which started in 2003 and has approx. 75.000 active participants at the moment.
What is CAPI? Interviews during which responses are recorded by respondents themselves (or an interviewer) with the aid of computers. This method is used in bigger samples to quickly gather opinions or present and rate computer-assisted stimuli (e.g. image worlds, product simulations, randomly generated rotations).
Typical applications? Measuring price thresholds, rating longer lists of statements, product simulations.
Limits to this method? Maximum interview length is 20 minutes; explorative questions shouldn't be asked; it's best to use the version where an interviewer is present for more complex research topics.
What are face-to-face interviews? In-person interviews during which an interviewer uses a structured questionnaire. As a rule, this method is used to gather the opinions of 100 to 200 people.
Typical applications? Pre-tests of TV and radio commercials and print ads; product and packaging tests.
Limits to this method? Maximum interview length is 30 minutes; pre-recruitment of respondents is required in the case of difficult target groups.
What is conjoint measurement? Computer-assisted survey in which several product features (attributes) in different attribute levels are randomly combined in product variants, whereupon willingness to buy and use is measured.
Typical applications? Measuring people's requirements of products and brands; identifying price thresholds; measuring the relevance of individual product features.
Limits to this method? Maximum interview length is 20 minutes; sets of explorative questions cannot be included; of only limited suitability for products that require a great deal of explanation.
