Target group research - methods of application
The basic criterion for dividing target group research is distinguishing between research conducted using quantitative and qualitative methods. The main objective of research conducted using the quantitative method is to collect numerical information that will then be used for further consumer analysis, while research conducted using the qualitative method focuses more on making observations and obtaining more precise opinions and descriptions than is the case with the quantitative method.
Types of quantitative research:
PAPI (Pen and Paper Personal Interview) - method in which the interviewer conducts paper-based interviews with respondents in the field.
CLT (Central Location Testing) - a type of research designed to test odors, tastes, and advertising.
CAPI (Computer Assisted Personal Interview) - research conducted using a computer and specially developed computer programs.
CATI (Computer Assisted Telephone Interviewing) - Computer assisted telephone interviewing allows for reaching a wide and diverse range of respondents.

CAWI (Computer Assisted Web Interviewing) - Because these surveys are conducted over the Internet, they can be carried out on large groups of people at low cost.
