Why are threats to internal validity, selectivity bias, statistical testing, and external validity important to evaluate in research literature?
Answer: The threats to the internal validity, selectivity bias, statistical testing, and external validity important to evaluate in research literature as it provides the information about the existence of relationship between the two variables. There are various threat to internal validity such as maturation, testing, controlling methods etc.
It can be identified by the internal validity. Selectivity bias and statistical testing provides the the reliability of the data so that it can be analysed. The external validity reveals about the standard of the research as it represents that the result shows about the entire population.

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
Control of the internal validity 1: The placebo effect of the internal validity can be cured by random assignment subject to both experimental and control placebo groups(Shader, 2017). 2: History threat can be removed by assigning random subjects to both control and experimental groups. 3: Maturation the third threat to validity can be handled with the help of the control groups of subjects which can change those in experimental groups. Assigning of random subjects can also be used. 4: Repeat...
