THE SOURCES OF RESEARCH DATA
- The design of the research project specifies both the data that are needed and how they are to be obtained.
- The first step in the data-collection process is to look for secondary data. These are data that were developed for some purpose other than for helping to solve the problem at hand.
- The data that are still needed after that search is completed will have to be developed specifically for the research project and are known as primary data.
- The secondary data that are available are relatively quick and inexpensive to obtain, especially now that computerized bibliographic search services and databases are available.
- The various sources of the secondary data and how they can be obtained and used are described ahead.
- Most secondary data are generated by specialized firms and are sold to marketers to help them deal with a category of problems.
- Nielsen’s television ratings, which marketers use in making advertising decisions, is the best-known example.
- Many of these services, broadly categorized as audits, commercial surveys, and panels, allow some degree of customization and thus fall between secondary and primary data.
- These sources are treated in detail ahead.
- An important source of primary data is survey research.
- The various types of surveys (personal, mail, computer, and telephone), are described ahead. Experiments are another important source of data for marketing research projects.
- The nature of experimentation, the types of experimental designs, and the uses and limitations of this method of obtaining data are also explained ahead
- Experiments are conducted in either a laboratory setting (most advertising copy pretests) or in a field setting (test marketing).
- Electronic and computer technologies have revolutionized both these environments, which are described later.
