Give 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
Homework Answers
Internal validity is concerned with the rigor (and thus the degree of control) of the study design. The degree of control exerted over potential extraneous variables determines the level of internal validity. Controlling for potentially confounding variables minimizes the potential for an alternative explanation for treatment effects and provides more confidence that effects are due to the independent variable. Eight threats to internal validity have been defined: history, maturation, testing, instrumentation, regression, selection, experimental mortality, and an interaction of threats.
External validity is the validity of
applying the conclusions of a scientific study outside the context
of that study. In other words, it is the extent to which the
results of a study can be generalized to and across other
situations, people, stimuli, and times.

Understanding the sampling process will contribute to your ability to critique research from a consumer's point of view. This week's Forum Discussion will help you to develop your sampling strategy based upon your PICOT. It should be approached in relation to the parameters or attributes of the study population, representative of the defined population, appropriateness of the sampling plan to the research design, appropriateness and justification of the sample size, and evidence that the rights of human participants (subjects) have...

Summarize below article 300 words no plagiarism. Thanks INTRODUCTION Informed consent is a decision to participate in research, taken by a competent individual who has received the necessary information; who has adequately understood the information; and who, after considering the information, has arrived at a decision without having been subjected to coercion, undue influence or inducement, or intimidation. Informed consent is a prerequisite for enrolling human subjects in biomedical research. The concept of “Informed consent” was enshrined in the Nuremberg...
