This discussion supports your understanding and application of the quantitative method and qualitative method of research approach. In your initial post, address the following:
- Differentiate between randomized and nonrandomized approaches to sampling populations. Discuss the importance of the role of sampling when conducting research.
Snowball sampling is a form of sampling where participants recommend people they know as research participants. Explain one pro and one con to this approach.
Discuss the usefulness of pretesting, pilot testing, or field-testing a survey or interview questionnaire.
- In some large-scale research projects the researcher is not always the one collecting data but is more heavily involved in the analysis and interpretation of the data. Would this create a challenge in a quantitative study where a survey was used for data collection? Would this scenario create a challenge in a qualitative study where a one-to one interview or focus group data collection method was used? Explain why or why not for both scenarios.
As you experienced in the Week 3 assignment, qualitative methods research can encompass some interesting forms of research approach to help us understand the human experience in society, such as ethnography. In the resources this week we asked you to review three other forms of approach that help us understand in unique ways: visual, documentary, and oral history.
After reviewing the resources provided, describe each form of approach. Explain their unique differences and similarities.
What is gained by conveying human experience via visual or audio as opposed to a written interpretation?
- Which form of approach did you find the most compelling in sharing the experience of humans in society? Explain why.
Do you think that these forms of visual and audio data evidence could be more powerful for influencing social change and public policy than written or statistical data? Explain your response.
- Your initial post should be at least 800 words in length. Support your claims with examples from the required material(s) and/or other scholarly resources, and properly cite any references.

Random sampling is a method of sampling where each element individually has a nonzero probability of being included in the sample from the sampling frame. Random sampling
also calls for awareness of the probabilities in question for the inclusion of each element. On the
other hand non-random sampling is a sampling methodology where chances are high you may
not have a frame of sampling at your disposal during the process of your market study. Therefore
the aspect of making sure that each element has an individual probability of being selected which
is non-zero is actually challenging. In this case, the researchers select the elements to be in the
sample using hypotheses based on the interests of the study (Ronald 2008).
Snowball sampling is a process where the participants of the research select other
individuals for a study or a te...
