Inferential Statistics

Question;1As you have been on this  journey, you have learned of the two main approaches in research – qualitative and quantitative. The line between quantitative and qualitative can be an interesting one because there is really no pure version of one or the other. Having an understanding of the essential differences between qualitative and quantitative methods can help in choosing the optimum study design and in balancing the two approaches.In your writing, carefully analyze the differences between each of the research approaches. Incorporate the advantages, disadvantages, and limitations that may be present for each approach using citations and references to validate your argument.2) In research, appropriate sampling is a critical component to maximize credibility and believability of results in order to generalize results to the population from which the sample was drawn.This prompt will focus on the following question: “If your goal is to generalize from a sample to a population, then which is more important: random selection or random assignment?” Explain your answer. In your writing, use appropriate citations and references to support your view.3) In the realm of statistics, it is known that a one-tailed test is more powerful than a two-tailed test. However, a cause and a situation exists for the use of both.In your writing, discuss different situations that would call for a two-tailed test over the one-tailed test as well as a one-tailed test over a two-tailed test, using citations and references to validate your argument.4) In research, the threat of internal and external validity is commonly discussed. However, some researchers view one more important than the other.In your writing, compare and contrast internal and external validity, and make a determination based on your research/reading for which of the two validity factors is most critical and why, using citations and references to validate your argument.5) Throughout your doctoral journey, you have touched on a critical component concerning ethical considerations.In your writing, discuss in detail why ethical considerations are so vital for credibility and believability in conducting research, using citations and references to validate your argument.
