QUANTIFICATION METHODS
Used to determine the measurable aspects of consumption: consumer
habits, audience ratings, market awareness and consumer attitudes.
A structured survey is used to recruit a representative sample.
The number of interviews depends on the segmentation and degree
of detail required by the client.
Personal interview: conducted
in the home, sales outlet or company headquarters.
Telephone interview: a computer
assisted process, using the CATI system. Results emerge quickly,
thanks to direct recording of interviews.
Mail survey: Reduces costs,
though it generates a lower response rate.
CIES makes closely monitored fieldwork the key to providing
reliable data.
Quantification methods are widely used in basic consumer
research and in assessing market size and segmentation.
SPECIFIC QUANTIFICATION METHODS
PANEL SURVEY:
For studies carried out at regular intervals, a fixed sample
may be used, though it must be renewed periodically.
OMNIBUS SURVEY:
A study in which clients buy their own share of the data.
This is a way of reducing costs among clients with the same
target universe.
SEMI-QUANTITATIVE METHODS
HALL -TESTS: This method is used when both descriptive and
quantitative data are required.
- They are conducted in public (superstores,
coffee bars, public lounges, etc.)
- The survey contains open-ended questions.
- Respondents may be asked to give
their opinion of a product or business after trial.
- Sample size is between 80 and 300
interviews.
- These tests are usually based on
personal interviews.

QUALITATIVE METHODS
Qualitative methods are used to investigate consumer motivation
and attitudes towards products or businesses.
The aim is to discover what motivates certain behaviour patterns
and what factors influence consumer decisions.
The main qualitative methods are:
- The in-depth or non-directive interview.
- The semi-structured interview.
- Focus groups.
- Projective techniques.
These methods are used for pre-campaign
testing, attitudinal and motivational studies and most kinds
of product testing in general.

DESK RESEARCH
When a stock of reliable data is already available, research
can be conducted from the office. This method, which is usually
combined with one of those described above, requires a well-known,
regularly updated database.
