In a short essay, list and discuss the five steps in the sampling design process
What will be an ideal response?
a. Define the target population - sampling design begins by specifying the target population. It is essential that the researcher precisely define the target population if the data generated are to address the marketing research problem. Defining the target population involves translating the research problem into a precise statement of who should and should not be included in the sample. The target population should be defined in terms of elements, sampling units, extent, and time frame.
b. Determine the sampling frame - a sampling frame is a representation of the elements of the target population. It consists of a list or set of directions for identifying the target population. A sampling frame can come from the telephone book, a computer program for generating telephone numbers, an association directory listing the firms in an industry, a mailing list purchased from a commercial organization, a city directory, or a map. If a listing is not readily available, it must be compiled.
c. Select a sampling technique - selecting a sampling technique involves choosing nonprobability or probability sampling.
d. Determine the sample size - determining the sample size involves both qualitative and quantitative considerations. Important qualitative factors that the researcher should consider in determining the sample size are 1. the importance of the decision, 2. the nature of the research, 3 . the number of variables, 4. the nature of the analysis, 5. sample sizes used in similar studies, and 6. resource constraints. As a general rule, the more important the decision, the more precise the information must be.
e. Execute the sampling process - execution of the sampling process refers to implementing the various details of the sample design. The population is defined, the sampling frame is compiled, and the sampling units are drawn using the appropriate sampling technique so as to achieve the required sample size.
