3 Methods of data collection
3.1 Focus Group Interviews
In a focus group interview, an objective discussion leader (or moderator)
introduce a topic to a group of respondents and directs their discussion of that
topic in a non-structured and natural fashion.
3.2 Case Study Method:
The Case study method is an-depth examination of a unit of interest. The unit
can be a customer, store, salesperson, firm, market area, website and so on.
By virtue of its insight-generating potential, the case study method is a useful
form of exploratory research.
3.3 Direct observation method:
The observational method involves human or mechanical observation of what
people actually do or what events take place during a buying or consumption
situation. It includes all lab experiments, done in Fisheries and aquaculture
sciences.
An Experiment is a procedure in which one (or sometimes more than one)
independent (or cause) variable is systemaffcally manipulated and data on the
dependent (or effect) variable are gathered, while controlling for other variables
that may influence the dependent variable.
A Laboratory Experiment is a research study conducted in a contrived setting
in which the effect of all, or nearly all, influential but irrelevant independent
variables is kept to a minimum.
A Field Experiment is a research study conducted in a natural setting in which
one or more inde~endent variables are manipulated by the experimenter .
