After studying the introduction to this unit and completing the study activities, briefly compare the uses of the research designs employed in the studies. What is each research design used to determine (for example, relationships between variables, differences among groups)? For one of the quantitative studies, summarize how the sampling, data collection, and data analysis procedures worked together to address the hypothesis. The post should be written in your own words, not direct quotes from the article. Incorporate material from the course text in a meaningful way.
The suggested length for this post is 400–500 words.
