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:By Day 4Post 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 reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Module 01 Assignment - Factors Affecting Nutritional IntakeModule 01 ContentHealthcare professionals would be thrilled if individuals made decisions about what to eat based on a solid knowledge of what constitutes a "healthy diet." Unfortunately, that is not typically the case. Many people do not know what constitutes a healthy diet. There are also those who do know but make less healthy choices for several reasons.The food choices that people make are influenced by a variety of factors. Factor-categories include, but are not limited to, environmental cues, socioeconomic realities, cultural/religious beliefs, and the availability of foods in the community.In a 3-page paper, written in APA format using proper spelling/grammar, address the following: Explain what nutrition is and why it is important.Describe the characteristics of a healthy diet and provide supporting examples.Identify at least two (2) factors (other than culture) that can impact a person's food choices and provide a specific example for each.Research a culture (e.g., ethnic, religious, dietary) where specific food restrictions are dictated and address the following:Describe the restrictions.Explain how the restrictions could make it difficult for an individual to achieve a healthy diet.What dietary alternatives could be incorporated to overcome the dietary restrictions?Cite at least 3 credible references and present the resources in APA format on the References page.
