Developing Sampling Plan
Question 1
Developing a sampling plan requires consideration of a number of factors: The frame, sampling unit, sample size, target population, precision, and stratification (Fowler, 2002; Leedy & Ormrod, 2005). Define the sampling methods of probability, both simple random and systematic. Evaluate the usefulness of sampling as applied in a quantitative research study in your field.
Introduction
This question addressed in this work is the development of a sampling plan which necessarily requires consideration of a number of factors including the frame, sampling unit, sample size, target population, precision and stratification (Fowler, 2002, Leedy & Omrod, 2005). This work will further provide a definition of the sampling methods of probability, both simple random and systematic and will evaluate the usefulness of sampling as applied in a quantitative research study in the field.
Frame
The sampling frame is the actual set of sampling units from which the sample or some stage of the sample has been selected or else acknowledged as the portion of the intended population” that could be incorporated in the sampling. The sampling frame is that which defines the sampled population (Herek, 2009). For example, in the instance of a simple random sample, all units from the sampling frame have an equal possibility to be drawn and to happen in the sample. In an ideal situation, the sampling frame should correspond with the population of relevance.
Sampling Unit
The sampling unit refers to the element or set of elements that were chosen in the sample for the purpose of the research study (Herek, 2009). In a simple single-stage sample, the sample unit is the same as the elements and in a multi-stage sample; the sampling unit can be households, individuals within the households and blocks.
Sample Size
Sample size refers to the number of elements, individuals or entities represented in the research study. (Herek, 2009)
Target Population
The target population is the set of units from which the sample is drawn and representative of in terms of the research study to be conducted. It is normally the ideal population to which the study results are to be arbitrary. For example, the target population could be set as all of the adult population of the United States (Herek, 2009).
Census or Sample?
Research is usually undertaken to obtain information about the characteristics or parameters of a population. A population comprises all the individuals or cases or elements that make up the universe of interest in the marketing research problem being studied. Information about the population may be obtained by taking a census or a sample. A census involves taking measurements from each and every member of the ...
