Which of the following should you consider when determining whom study results would apply to?

Whether the exposure itself varies across populations

Whether the physiology of the exposure/outcome association would vary across populations

Whether the study results are internally valid

All of these

Why is internal validity more important than external validity?

	Because internal validity is determined by statistical significance.
	Because if results are not internally valid, they cannot be generalized to anyone.
	All of these are correct
	Because most study results can be generalized to many different populations.

Which of the following would make for a smaller p-value? Select all that apply:

A	A larger sample size
B	A smaller sample size
C	A larger effect size
D	A smaller effect size
E	The internal validity of the study
F	The external validity of the study
