The work of collecting original data is usually limited by time, money and manpower available for the study.

Advantage at primary data :

Ø It ensures more accuracy
Ø It represents current information
Ø According to research problem, data can be collected, thus these data are more dependable
Ø Source at data can easily be identified.
Disadvantage of primary data
Ø It takes time
Ø Collection cost is high
Ø Informants may confure researcher
Ø Collection process is very involved
Ø Sometimes it becomes risky for researcher.
Ø Reaction can be possible from the source of data.

Advantage of second Data :

Secondary data can help researcher Secondary data can help researcher to
Ø I dentify the problem
Ø Define the problem better
Ø Develop an approach to the problem
Ø Formulate an appropiate research design
 Answer certain research questions and test some hypotheses
Ø Interpret primary data more insightfully

Disadvantages of secondary data :

Because secondary data have been collected for purposes other than the problem at hand, their usetuleness to the current problem may be limited in several important ways, including relevance and accuracy. The objectives, nature and methods used to collect the secondary data may not be appropiate to the present situation. also secondary data may be lacking in accuracy or they may not be completely current or dependable.

Collection of Primary Data :

The primary data are collected during the course of doing experiments in an experimental research but in case we do research of the descriptive type and perform serveys, whether sample surveys orcensus surveys, there we can obtain primary data either through observation or through direct communication with respondents in one form or another or through personal interview. There are several methods of collecting primary data, particularly in surveys and descriptive researcher which are described below:
