<span>A sociologist might look at the amount of fresh fruits and vegetables available in a neighborhood trying to understand social issues that affect health. If you can find and afford to live in a neighborhood where you can shop for fresh fruits and vegetables more often, near home, you may be more likely to consume those foods more regularly.</span>
<u>Marginal Costs & Marginal benefits in a choice you made.</u>
Assume that I want to buy an ornament for hands. I spend $500 for purchasing an ornament. When I was supposed to see another I wish to buy that. But spending again for the ornaments also not a good idea. I am also not willing in spending $500 for the ornament. So, I decided to go for an ornament that costed only $250. No, my marginal benefit get decreased from $500 to $250. When I decided to go fro the second one or more than one of same good my marginal benefits decrease.
Marginal cost is something that changes in a smaller range in the production of one additional unit. For example I decide to manufacture 500 pens. i need raw materials for the production and a building and machine for production. The change in the cost or expenses that happens when I decide to produce 600 pens is the marginal cost.
Answer:
Case study
Explanation:
A case study is a kind of study used in social sciences in which the researcher observes an individual/group/event in a very in-depth manner. Case studies give a lot of information about the person or group who is being studied and let the researcher make causal inferences (because of the in-depth observation) and the researcher gets a better understanding of the situation.
In this question, the psychologist faces an ethical dilemma of needing to remove a potentially beneficial treatment. However, using a case study, she wouldn't need to do so because she could observe the autistic child in his environment without changing it, because the case study is an observing explanatory study. Therefore, the ethical dilemma would be eliminated and she could draw conclusions from the study.
