Explanation / Answer

1) A research study is the complete in depth analysis on a specific area. It is considered extremely important in various fields .For example , business research study can be very useful in analyzing the market and demand for the new product.

2)Questionary method is used to collect primary data by using the following sources.

Projective techniques like word association test

Sentence completion test.

Product test.

Diaries.

Omnibus studies.

Structured method.

Unstructured method.

3) Hypothesis may be defined as a proposition or set of propositions set forth as an explanation for the occurrence of some specified group of phenomenon either asserted merely as a provisional conjecture to guide some investigation or accepted as highly probable in the light of established facts.

In order to make the decisions it is necessary to make certain assumptions about the population parameters.These assumptions are referred to as hypothesis.E

Ex: Students who take tutions perform better than the others who not receive tutions.

To test the above hypothesis we have to use testing of hypothesis.

4) Exploratory research is often conducted because a problem has not been clearly defined as yet or it's real scope is unclear.

It is the intial research , before more conclusive research is undertaken

Exploratory research can be quite informal , relying on secondary research such as reviewing available literature or qualitative approach with Consumer's, employees, management.The results of this are not useful for decision making by themselves, but they can provide significant insight into a given situation.

5) Response methods :

Mail intercept response.

Center location telephone response.

Self administred response.

Mail response.
