Answer: It would unethical to conduct some types of experiments on people
Explanation: Experiment as such serves to test a hypothesis, and based on the results obtained by the experiment confirm it, i.e become a theory. So experiments are needed to prove some of the assumptions, and the results obtained are knowledge that becomes part of the theory, so research is, in fact, a means of acquiring knowledge that is important for the theory.
Of course, knowledge is best if it is obtained by observing some of the phenomena being studied and researched, because empirical experience is the best confirmation of some scientific premise.
And while experiments are appropriate to the limits of humanity, it is inappropriate and unethical to go and subject people to experiments beyond that limit for research. Imagine testing a virus that is not sufficiently researched, and an experiment is conducted on people how they will tolerate it. First of all, this is not humane, it is not ethical, and it is not safe for these people, since it is still an unknown and untested virus.
Tobacco was the foul weed.
The correct answer is: No, because the lack of assignment of communities to different levels of country music listening means there is a possibility of lurking variables.
Causation can only be determined in this case if the researchers randomly assigned different amounts of country music to different communities. They did not do this, so the study design doesn’t rule out lurking variables.
Due to their belief that economic success is the result of human work and that mobility is attainable, Americans have traditionally tolerated significant gaps between wealthy and poor persons.
Mobility is strength throughout a muscle's range of motion. Flexibility and mobility vary in that you can control your range of motion with mobility. For instance, with the help of your arms, you can certainly elevate your leg fairly high.
When you are Mobility, you can lift your leg up on your own without the aid of another person. You can control the whole range of motion of your leg with just your leg muscles.
You can have muscle strength even with a limited range of motion. Since you need to train the complete range of motion to develop mobility, strength alone is insufficient.
