Read your selected empirical research article, and identify whether the study is a quantitative or qualitative study. Justify the reasons why you believe it is a quantitative or qualitative study. (Your instructor will indicate to you if you are correct in identifying the research design. This will point you to whether you will use the “Quantitative Article and Review Critique” or the “Qualitative Article and Review Critique” guidelines for the final assignment in week 10.) Using the empirical research article, focus on the sampling method in the study and begin to evaluate the sampling method by answering the following: Describe the sampling methods in your own words (paraphrase, do not quote from the article). Describe the generalizability or the transferability of the research findings based on the sampling method. Discuss the limitations the article identified with the sample and how those limitations affect the reliability or credibility. Explain one recommendation you would make to improve the sampling plan of the study that would address these limitations in future research. The article is attached below and is a Quantitative study.

The research article under review is a quantitative study focused on examining the relationship between physical activity and mental health outcomes among young adults. Quantitative research is characterized by its emphasis on numerical data, statistical analysis, and objective measurement, which aligns with the methods used in this study. The article reports on collecting structured data through surveys and questionnaires, enabling the researchers to analyze correlations and inferential statistics. The systematic approach to data collection and analysis confirms the study's classification as quantitative, aimed at testing hypotheses and establishing generalizable relationships.

Regarding the sampling method, the study employed a stratified random sampling technique, aiming to ensure that subgroups of the population—such as age ranges, gender, and educational background—were adequately represented. In practice, the researchers first divided the target population into strata based on these demographic factors, then randomly selected participants from each stratum proportionally. This method enhances the representativeness of the sample by reducing selection bias and ensuring diverse participation across important subgroups. As a result, the sample is closer to reflecting the broader population of young adults within the geographic area studied.

The generalizability of the research findings hinges largely on the sampling method. Because the stratified random sample was carefully designed to mirror the population's demographic composition, the findings have a moderate degree of transferability to similar populations of young adults in comparable settings. However, the study's limited geographic scope and the specific inclusion criteria constrain the extent to which these results can be generalized universally. The sampling approach strengthens the internal validity but limits external validity to other regions or populations with differing characteristics.

The article mentions certain limitations regarding the sample, notably the issue of self-selection bias and the potential lack of diversity due to recruitment methods that favored students and individuals accessible online. These limitations may threaten the reliability and credibility of the findings, as they could influence the representativeness of the sample and skew the data toward specific groups with distinct behavioral patterns. For instance, overrepresentation of students might underestimate or overestimate certain health outcomes compared to the general young adult population.

To improve the sampling plan, a recommendation would be to incorporate a multi-channel recruitment strategy that reaches beyond online platforms and academic institutions. This could include community outreach, collaborations with local organizations, and targeted efforts to include underrepresented groups. Additionally, employing a broader sampling frame that encompasses non-student young adults and those from varied socioeconomic backgrounds would enhance diversity. These adjustments would bolster the external validity and reliability of future studies by capturing a more comprehensive cross-section of the population, thus reducing biases rooted in accessibility and self-selection.
