- What technique would the researcher chose to increase external validity of a study?
Homework Answers
One of the best technique to increase the external validity of a study is by doing an experiment in the area where the study is to be done. This can enable to assess what is needed and what has to be avoided in order to conduct a successful study .The biases can be known in prior and appropriate actions can be done.

Question 4 The difference between internal and external validity is best described as: Internal validity tells us if the inferences drawn from the study population are true of the study population whereas external validity tells us if the inferences drawn from the study population are true of the target population. Internal validity tells us if the inferences drawn from the population being studied apply to other populations whereas external validity tells us if the inferences drawn from the population being...

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
