Data collection methods

Four methods, one field team.

We run PAPI, CAPI, CATI and CAWI fieldwork with our own team. We choose the right method for your project with you and combine methods in one project when needed.

Comparison

Four methods side by side

A general table for a first idea. Once we see your target audience and questionnaire, we recommend the set-up that fits best.

Mixed mode

Several methods in one project

Some audiences are hard to reach through one channel. In that case we combine methods: on tablets in city centres, on paper where connectivity is weak, and by phone for respondents who can’t be reached face to face.

In a mixed-mode set-up, the questionnaire must follow the same flow in every channel and the data must merge into one structure. We plan this before going into the field.

  • CAPI
  • CATI
  • CAWI
One data structure
Data collected with four methods merges into one data structure.
