Many infrastructure projects, large and small, have been planned in the past without specific recognition of economic objectives and without explicit benefit-cost analyses to justify their implementation, provide examples of such projects.
Market research can be categorized into two major categories namely primary and secondary research.
Primary research is the one which provides direct feedback/opinion of the population that needs to be analyzed. It is the research which undergoes first-hand data. This is because the reliability and validity of primary data is more which makes the conclusions more accurate. However, the reliability and validity are subject to the research ethics being followed properly.
The examples of primary data collection methods are:
Survey
Personal interview
Observations
Secondary research is the one which is not based on primary data. It is the data that is taken from various sources such as company’s website, newspapers, and other sources. The reliability of this data is subjected to the accuracy of the source from where it is taken.
Some examples of secondary sources are:
Already existing research works
Magazines
Newspapers
Websites
