5-2 Discussion: Proper Sampling
Previous Next
In your initial post, consider what you have read in the assigned Chapter 2 sections of the textbook and identify your own example of improper sampling from your day-to-day life (try not to repeat examples shared by your peers). Be sure to provide the sampling method used, why the sampling method is improper, what type of sampling should have been used, and why.
In your response posts, discuss the implications of the improper sampling examples posted by your peers. For example, what sorts of incorrect conclusions could you draw from the investigations? How would you correct the sampling errors in the examples? Try to draw connections to your final project research article: is there any room for improvement of the sampling methodology?
To complete this assignment, review the Discussion Rubric document.

Answer
Improper Sampling
An example of improper sampling is in a case where researcher meets people in a certain place and makes them research subjects. A researcher moves to a nearby Park at noon, and interviews people in regards to consumer satisfaction with certain product or service is a common occurrence in business research.
This kind of sampling method is called convenience sampling (a non-probability or non-random sampling method where researcher choses a sample that is readily available by use of a non-random or non-probabilistic method) (Sedgwick, 2013). The researcher finds the nearby Park to be readily available, with people that will not take much effort reaching being subjects for the research. The impropriety of this sampling method is in its bias – the inherent bias that it will not represent the entire population. In this example, the location and time of day are especial factors that will create a bias by profiling the kind of people being interviewed. Notably, similar kinds of people attend Parks at noon, to take cool of the scorch. Therefore, these people will likely have similar kinds of idea in regards to the subject, will pose a skew in extrapolation to represent the entire population. Therefore, it curtails the possibility of generalizing the outcome of the research.
In this case, a simple random sampling technique should have been used to take care of the bias, because of its probabilistic nature – hence sufficient representation of the population is attained.
