3. Secondary Data - Overview Secondary data are pieces of information that have already been collected for a different purpose, but may be relevant to the research problems at hand. Primary data, in contrast, are survey, observation, or experimental data collected to address the problem currently under investigation.

4. Importance/Usefulness Secondary data are useful for addressing a number of research questions, for example: Secondary data are useful for addressing a number of research questions, for example: Estimating market potential Estimating market potential Analyzing competitors Analyzing competitors Sales forecasting Sales forecasting Assessing industry trends Assessing industry trends Alerting the manager to potential problems Alerting the manager to potential problems Providing preliminary information to guide subsequent primary data collection Providing preliminary information to guide subsequent primary data collection Hollywood stock exchange

5. Advantages of Secondary Data Low Cost Low Cost Less Effort Less Effort More Timely More Timely Some info is available only from secondary data sources; for example: Some info is available only from secondary data sources; for example: Market shares Market shares Industry data from trade associations Industry data from trade associations

6. Sources of Secondary Data There are two key sources of secondary data: The Company Itself (Internal Databases ) Other Organizations or Persons (External Databases)

7. Internal Databases Database Marketing Database Marketing Is the creation of large computerized files of customers’ and potential customers’ profiles and/or purchase patterns. Is the creation of large computerized files of customers’ and potential customers’ profiles and/or purchase patterns. Is the fastest-growing use of internal database technology.

10. Other Sources of Secondary Data Geographic Information Systems Geographic Information Systems Computer-based systems that use secondary and/or primary data to generate maps that visually display answers to research questions.

11. Some Useful Numbering Systems – SIC & UPC SIC (Standard Industrial Classification) is an uniform numbering system for classifying establishments according to their economic activities. Total economy is divided into 11 divisions (manufacturing/mining etc...) which are further divided into major groups and subgroups. Example: SIC (Standard Industrial Classification) is an uniform numbering system for classifying establishments according to their economic activities. Total economy is divided into 11 divisions (manufacturing/mining etc...) which are further divided into major groups and subgroups. Example: 57= Home Furniture, Furnishings 57= Home Furniture, Furnishings 571= Home Furniture and Furnishing Stores 571= Home Furniture and Furnishing Stores 5715= Furniture Stores 5715= Furniture Stores Government and several non-govt. industrial data are organized by SIC codes now being replaced by North American Industrial Classification Codes (NAICS) Government and several non-govt. industrial data are organized by SIC codes now being replaced by North American Industrial Classification Codes (NAICS) UPC: Numbering system used in consumer goods UPC: Numbering system used in consumer goods

13. Limitations of Secondary Information Lack of Availability Lack of Availability For some research questions there are simply no available data. For example, if Kraft General Foods wanted to evaluate the taste, texture, and color of three new gourmet brownie mixes, there are no secondary data that would answer these questions.

14. Limitations of Secondary Information Lack of Relevance Lack of Relevance May be measured in units that cannot be used by the researcher.
