The design of a research study is based on the purposes of the study. If descriptive information is needed, then a quantitative study is likely to be undertaken; if the purpose is to get new ideas (e.g., for positioning or repositioning a product), then a qualitative study is undertaken.
A search for secondary data generally follows the statement of objectives. Secondary information is any data originally generated for some purpose other than the present research objectives. (Original data performed by individual researchers or organizations to meet specific objectives is called primary data.) Secondary data includes both internal and external data. External secondary data consists of any data collected by an outside organization.
