Probability And Nonprobability Are The Two General Categories Of Samp

Probability and nonprobability are the two general categories of sampling. Probability sampling uses random selection, whereas nonprobability sampling does not. For example, if you wanted to study the effects of divorce on the psychological development of adolescents, you could gather a population of a certain number of adolescents whose parents were divorced. Then, out of that population, you could randomly select 25 of those people. If you wanted to use nonprobability sampling, you would choose specific people who had met predetermined criteria.

Consider your own proposed study: Which of these sampling techniques might be best for your purposes? In this Discussion, you identify the population, sample, and sampling technique for your study. You then consider ethical or cultural issues related to the population that you should address. To Prepare: Review the Learning Resources on sampling in research and on ethics related to vulnerable populations.

By Day 3 Restate your research question and your chosen methodological approach. Then, identify the population, sample, and sampling technique that would best address your research question and approach. Justify your choices. What are some ethical and cultural concerns that need to be addressed with this population if studied? Please use the Learning Resources and the NASW Code of Ethics to support your post (i.e., cite and reference).

By Day 6 Respond to two colleagues by providing feedback on their choice of population, sample, and sampling technique. How do their choices fit with the research question and research methodological approach? Please use the Learning Resources and the NASW Code of Ethics to support your response (i.e., cite and reference).

Paper For Above instruction

The research question I am proposing to investigate is: "How does participation in community-based mental health programs influence the resilience of young adults experiencing homelessness?" My methodological approach will be a mixed-methods design, combining quantitative surveys with qualitative interviews, to gain comprehensive insights into the impact of such programs.

For this study, the population consists of young adults aged 18 to 25 who are currently experiencing homelessness and are participating in community-based mental health programs within a metropolitan area. This specific population is appropriate because it directly relates to the research question, focusing on a vulnerable group whose resilience may be impacted by external support systems. Ethical considerations include ensuring the confidentiality and voluntary participation of individuals in this vulnerable group, aligning with the NASW Code of Ethics, which emphasizes respect for clients' dignity and privacy (National Association of Social Workers, 2017). Cultural sensitivity is also vital, considering the diverse backgrounds of participants, which necessitates culturally competent approaches in both recruitment and data collection.

The choice of sampling technique is primarily purposive sampling, a nonprobability method, because it allows targeted recruitment of participants fitting specific criteria, such as age, homelessness status, and participation in mental health programs. Purposive sampling ensures that participants are relevant to the research purpose, maximizing the depth of insights obtained. Although probability sampling like simple random sampling could enhance generalizability, logistical challenges and ethical concerns—such as the difficulty of obtaining a complete sampling frame of this transient population—make purposive sampling more suitable.

Addressing ethical and cultural issues is critical in this study. Respecting participants' autonomy by ensuring voluntary participation and the right to withdraw aligns with the NASW Code of Ethics. Privacy concerns are paramount, especially given the stigmatized nature of homelessness and mental health issues; confidentiality must be rigorously maintained. Culturally, it is essential to acknowledge and respect the diverse backgrounds of participants, which may influence their perceptions and experiences with mental health services. Culturally competent researchers will need to develop rapport and trust to facilitate honest disclosures. Overall, the chosen sampling method and ethical considerations aim to uphold the integrity of the research while protecting participants' rights.
