The content of the interview therefore should specifically reflect the interview's objectives. It should answer the questions that Jason wants answered.
Criterion-related validity should also be considered. Jason needs to ensure that the information he is trying to gather would be available and reliable. This can be difficult because he is trying to gauge reactions of his subjects. Construct validity also needs to be considered. Convergent validity is required -- he must understand how the attitudes of the townsfolk different from those of the general population. Thus, he must have a comparable. He may therefore need to conduct his survey with the general population to use as a comparable. Discriminant validity will also need to be examined, to ensure that the responses are independent of any bonding between the interviewer and interviewee.
The next step to developing internal validity is to ensure that there are few error sources -- to build better reliability. Respondents, for example, may not understand some terms or concepts, and therefore could give an answer that they do not intend as a result. Thus, key terms and phrases must be defined. In particular, Jason has reason to believe that lack of knowledge itself is an obstacle, so he needs to bridge this gap if he is to get accurate responses to his questions -- or he needs to test for the impact of a lack of knowledge on the community members' attitudes. To guard against errors originating from the interviewer, professional interviewers should be used. For example, Jason noted...
Business Research Research into the legalization of marijuana will seek to determine what people's views on the issue are. The population is going to be the entire United States, as we are seeking to determine national views about the issue. The sampling will be done at random, using databases of phone numbers and computer-generated dialing. The operators will only know of and gather non-personal information such as age bracket, gender and
It is projected that at least 10% of the individuals receiving the survey will respond. There are a variety of reasons for using qualitative methods in a study such as this one. Even though there are drawbacks to the qualitative method including (but not limited to) the fact that respondents are not known and could be lying, the responses are very subjective, and the questions themselves are quantitative in nature,
Business research process is unique in that it may be tailored to individual types of organizations and their needs. For example, business research for a large, multinational pharmaceutical company would have slightly different needs than that a local fast-food franchise group. However, there are six basic steps that most every business research project should cover: Appraisal -- Before any research can be done, it is important to do an honest assessment
One business research method that has been used to good effect by some companies is the data envelope analysis methodology developed by Charnes and his colleague (1978, cited in Marcoulides at p. 122). According to Marcoulides (1998), "This method is used to evaluate the relative efficiency of a set of decision-making units (DMUs)" (p. 122). The term "decision making unit" was coined by Charnes and his associates to describe a
Business Methods In order to study career aspirations, a survey of fifteen students was conducted to determine what level the student expected to achieve as their highest level. The students polled were all business students. The unit of analysis was scalar, with the options reflecting hierarchical levels within a corporation. The results of the survey were as follows: Executive Upper Management Middle Management Lower Management Non-Management These results show that business students have a wide range of
Business Tools The information presented (Ch. 12) notes that the perception of respect is an important determinant of customer satisfaction. The company, Campbell-Ewald, used surveys to determine the importance of respect to customer loyalty, and further linked loyalty to purchasing. The company's surveys sought to operationalize respect using a number of questions. Its output is a set of five "people principles" that it believe are correlated with customer perception of respect.
