Designing Quantitative Research

Question description

Researchers consider validity and reliability with each new study they design. This is because validity and reliability are not fixed but rather reflect a particular study’s unique variables, research design, instruments, and participants.

In the context of research design, two types of validity, which speak to the quality of different features of the research process, are considered: internal validity and external validity. Assuming that the findings of a research study are internally valid—i.e., the researcher has used controls to determine that the outcome is indeed due to manipulation of the independent variable or the treatment—external validity refers to the extent to which the findings can be generalized from the sample to the population or to other settings and groups. Reliability refers to the replicability of the findings.

For this Discussion, you will consider threats to internal and external validity in quantitative research and the strategies used to mitigate these threats. You will also consider the ethical implications of designing quantitative research.

With these thoughts in mind:

WRITE an explanation of a threat to internal validity and a threat to external validity in quantitative research. Next, explain a strategy to mitigate each of these threats. Then, identify a potential ethical issue in quantitative research and explain how it might influence design decisions. Finally, explain what it means for a research topic to be amenable to scientific study using a quantitative approach.

Be sure to support your Main Issue Post and Response Post with references to the  Learning Resources and other scholarly evidence in APA Style.

What were the consequences of the Spanish-American War (War of 1898) for American foreign policy

Question description

An ideal post would be two solid paragraphs (that includes a thesis statement, a body of supporting evidence, and a conclusion that summarizes the main points). The post should be well constructed and free of grammatical errors, and be between 250 and 300 words. You do not need to undertake outside research in order to answer the question; although you may, if you like. It is a wise strategy to create your response as a Word document (that way, you have a copy for yourself). You must cite your sources both in your response and below it (Bibliography), using the Chicago Style citation format. Students who do not cite their work can expect to receive only a minimum grade of 60% for this assignment. It is expected that our textbook by Shi and Tindall will be a source and should likewise be accessed and cited.

The book required is below:

David E. Shi and George Brown Tindall, America: A Narrative History, Vol. 2, 10th ed. (New York: W.W. Norton, 2016) [ISBN: 9780393265958].
