Week 3 Discussion Posts
Kindly include references
Discussion 1: Week 3: Manifest Destiny
Why did the Mexican War of 1846 take place? Was the war necessary? Was it a good thing? What does this war tell us about this period of American history? Was it God’s plan that the U.S. extend from the Atlantic to the Pacific, or were imperialists looking for a way to defend what they planned to do anyway? Elaborate.
Discussion 2: Week 3: The Market Revolution
Discuss America’s transportation revolution that took place during the first half of the 1800s, including the development of roads, canals, railroads, and steamboats. How did they contribute to the “market revolution?” Elaborate.
Discussion 3: Week 3: Research Problems, Designs, and Sample
This week’s graded discussion topic relates to the following Course Outcomes (COs). 
CO2 Apply research principles to the interpretation of the content of published research studies. (POs 4 and 8)
CO4 Evaluate published nursing research for credibility and lab significance related to evidence-based practice. (POs 4 and 8)
This week, we will discuss the research design and sample for your nursing clinical issue. The research design flows from the research question and outlines the plan for the study that will answer the research question. The design identifies the major components of the study. It is important to remember that there is no one best design for a research study.
After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer.
The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings?
