Answer:
This is my original response
Explanation:
I would use non-probability sampling to find a large enough population to accurately and effectively represent a range of age, occupation, and anxiety levels among both genders. The hypothesis would be constructed around predicting the effectiveness or lack thereof of the new drug among a certain population. The operational definition of anxiety could be in terms of a test score or by plotting the activation of the sympathetic nervous system. The independent variable would be the administration of a placebo or the actual test drug. The dependent variable would be the test scores or how the sympathetic nervous system is impacted and changes in activation. The experimental group and control group would ideally be split evenly between the range of age, occupation, and anxiety levels among both genders from the sampling population. The experimental group would get the real test drug and the control group would get the placebo.
