4.1 Research Approaches
One of the questions that an organization must decide before conducting research is which research approach will be most appropriate. The approach chosen will depend on the research question and the type of information is seeking. There are three general research approaches; descriptive, exploratory and causal (Kolb, 2008).
Descriptive research
Descriptive research is used when statistical data are needed on a fact. The tool used to conduct descriptive research is almost always surveys (Kolb, 2008).

Exploratory research
Researchers should use exploratory research when a research question deals with finding information on consumer attitudes, opinions and beliefs. Such exploratory research can be useful even when

Nonprobability Sampling Methods
All of the sampling methods we have described thus far embody probability sampling assumptions.
In each case, the probability of any unit being selected from the population into the sample is known, even though it cannot be calculated precisely.

In our study, we consider convenience sampling procedure when selecting consumers. Moreover, for selecting farmers and middlemen we apply judgement sampling procedure.

Developing a Sample Plan
Up to this point, we have discussed various aspects of sampling as though they were discrete and seemingly unrelated decisions. However, they are logically joined in a definite sequence of steps, called the sample plan, which the researcher goes through to draw and ultimately arrive at the final sample. These steps are listed and described in Table .
