Hinweis der Redaktion
- This chapter explains the use of secondary data sources to develop and formulate research questions.
- See the text Instructors Manual (downloadable from the text website) for ideas for using this research-generated statistic.
- Exploration is particularly useful when researchers lack a clear idea of the problems they will meet during the study. Through exploration researchers develop concepts more clearly, establish priorities, develop operational definitions, and improve the final research design. The exploratory phase usually consists of one or more of the search strategies detailed in the slide. Discovery and analysis of secondary data sources include published studies, document analysis, and retrieval of information from organization’s databases. Expert interviews are interviews with those who knowledgeable about the problem or its possible solutions. IDIs are interviews with individuals involved with the problem. Formal or informal group discussions may also be held. Most researchers find a review of secondary sources critical to moving from the management question to the research question.
- Exhibit 5-1 suggests that exploration of secondary sources can be useful at any stage of the management-research question hierarchy.
- This slide details the objectives that should be accomplished during the exploratory research phase of a project. Expand understanding of management dilemma Gather background information Identify information that should be gathered Identify sources for and actual questions that might be used Identify sources for and actual sample frames that might be used
- Generally, the exploration phase will begin with a literature search. A literature search is a review of books, journal articles, and professional literature that relate to the management dilemma. This may also include Web-published material. This slide details the five steps of a literature search. The result of a literature search could be a solution to the management dilemma. If so, no further research is necessary. Otherwise, a research proposal is generated.
- Researchers often meet to discuss symptoms when developing the management-research question hierarchy.
- Information sources are categorized into three levels. Primary sources are original works of research or raw data without interpretation or pronouncements that represent an official opinion or position. Secondary sources are interpretations of primary data. A firm searching for secondary sources can search either internally or externally, as depicted in Exhibit 5-2. This exhibit is shown on the next slide. Tertiary sources are aids to discover primary or secondary sources or an interpretation of a secondary source.
- Exhibit 5-2 This slide illustrates some of the possible internal and external secondary sources. To verify that students understand each of the types of sources, ask them for examples.
- The U.S. Government is the world’s largest source of data. This ad promotes access to government data.
- These are the five types of information sources used most by researchers at this phase of a project. Indexes and bibliographies help one to identify books and journal articles. An index is a secondary data source that helps to identify and locate a single book, journal article, author, etc. from a larger set. A bibliography is an information source that helps locate a single book, article, photograph, etc. Dictionaries are secondary sources that define words, terms, and jargon. Encyclopedias are secondary sources that provide background or historical information about a topic. A handbook is a secondary source used to identify key terms, people, or events relevant to the management dilemma or management question. Directories are reference sources used to identify contact information.
- A researcher using secondary sources will want to conduct a source evaluation. Marketers should evaluate and select information sources based on five factors. Purpose is the explicit or hidden agenda of the information source. Scope is the breadth or depth of topic coverage, including time period, geographic limitations, and the criteria for information inclusion. Authority is the level of the data (primary, secondary, tertiary) and the credentials of the source author. Audience refers to the characteristics and background of the people or groups for whom the source was created. Format refers to how the information is presented and the degree of ease in locating specific information within the source. Students often accept web-delivered information as of the same quality as electronic databases. One exercise is to have them view a web-site and present an analysis of it using the five factors. Students are often active participants in blogging, so having them use such a site for analysis might open their eyes. Exhibit 5-3 offers several questions to answer when evaluating web sites on the five factors.
- Exhibit 5-4: Data mining is a type of record analysis. It uses mathematical models to extract meaningful knowledge from integrated databases. This Exhibit discusses the evolution of data mining.
- Early use of data mining was still being driven by our search for understanding of customers, as noted by the emphasis on marketing’s use of data mining (green bars). Business also does a lot of data mining in search of greater profitability (financial analysis=yellow bar). Operations use was growing (gold bars). Notably absent was Human Resources use of data mining.
- Exhibit 5-5 The data mining process involves five steps: sample, explore, modify, model, and assess. In the sample step, the researcher decides between census data and sample data. Explore involves identifying relationships with the data. In the third step, data are modeled and/or transformed. In the fourth step, a model is developed that explains the data relationships. Finally, the model is tested for accuracy.
- Exhibit 4-1 illustrates the research process. This slide focuses on the first stage of the process, clarifying the research question. A useful way to approach the research process is to state the basic dilemma that prompts the research and then try to develop other questions by progressively breaking down the original question into more specific ones. This process can be thought of as the management-research question hierarchy. The process begins at the most general level with the management dilemma. This is usually a symptom of an actual problem, such as rising costs, declining sales, or a large number of defects. Exhibit 3-2 illustrates the formulation of the research question for MindWriter. A management question is a restatement of the manager’s dilemma in question form. A research question is the hypothesis that best states the objective of the research; the question that focuses the researcher’s attention. An investigative question is the question the researcher must answer to satisfactorily answer the research question. A measurement question is the question asked of the participant or the observations that must be recorded.
- Exhibit 5-6 The management-research question hierarchy process is designed to move the researcher through various levels of questions, each with a specific function within the overall marketing research process. This multi-step process is illustrated in the slide. An example is provided on the following slide. The role of exploration in this process is depicted in Exhibit 3-4, located on Slide 3-9.
- Exhibit 5-7 Declining sales is one of the most common symptoms serving as a stimulus for a research project. SalePro, a large manufacturer of industrial goods, faces this situation. Exploration 1 reveals that sales should not be declining in the South and Northeast. Environmental factors there are as favorable as in the growing regions. Subsequent exploration leads management to believe that the problem is in one of three areas: salesperson compensation, product formulation, or trade advertising. Further exploration (4) has SalePro management narrowing the focus of its research to alternative ways to alter the sales compensation system, which (5) leads to a survey of all sales personnel in the affected regions.
- This slide depicts how exploration leads back into the formulation of management questions and research questions. Examples of management questions are provided on the next slide.
- This table shows examples of management questions that might flow from general questions, some drawn from Exhibit 5-9.
- A research question best states the objective of the marketing research study. Incorrectly defining the research question is the fundamental weakness in the marketing research process. After the exploration process is complete, the researcher must fine-tune the research question. At this point, the research question will have evolved in some fashion. It will have better focus. In addition to fine-tuning the original question, other research question-related activities should be addressed in this phase to enhance the direction of the project. Examine variables to be studied and assess whether they are operationally defined. Review the research questions to break them down into second and third-level questions. If hypotheses are used, be sure they meet the quality tests. Determine what evidence must be collected to answer the various questions and hypotheses. Set the scope of the study by stating what is not a part of the research question.
- This ad from Harris Interactive promises that if this guy is your customer, you’ll actually understand what makes him tick.
- A Gantt chart is a common project planning tool that reveals summary tasks, benchmarking milestones, and detailed tasks against a time frame for the overall project. Tasks may be color coded to indicate a particular team member’s responsibilities. Many project-management software packages include Gantt charting. The chart may be used to monitor projects to keep them on time, as well as to alert the client or manager to steps requiring their approval—and what happens to the project’s schedule if approval is not forthcoming when it is needed.
- This chapter explains the use of secondary data sources to develop and formulate research questions.
- Exhibit 5a-1
- Exhibit 5b-2 The basis of searching is understanding how electronic databases are constructed for search. This exhibit is designed to provide the student with a 2-step process for writing advanced query statements using Boolean language. Each database has its own structure so students should always read the material provided by the particular provider about connectors, limiters, truncation symbols, etc. Students should also be encourage to search more than one database using the same search query.
- Exhibit 5b-1: If you do a day in the library or the computer lab, using this exhibit and the one on the previous slide is a good way to teach the development of query or search statement.
