Marginal beneficit and marginal cost are economic concepts. On the one hand, the marginal beneficit is defined as the added satisfaction a consumer gets from an additional unit of a good or service. On the other hand, the marginal cost is the change in total cost that results from making or producing one additional item.
The consumer could use these measurements to consider whether the cost is higher than the benefit when purchasing an item or getting a new service. Do they really need to buy an extra t-shirt when they already have enough of them? The benefit would be that they would get another t-shirt. In addition, as this is a new piece of clothing, it would probably be more in fashion than the old ones. However, the consumer would have to spend an amount of money that perhaps he had saved for another purpose and consequently would lack money for it. If he decided not to buy the t- shirt, he would have said amount of money to pay for his taxes or services. The same applies when it comes to the extra smoothie. The amount of money spent on the smoothie could be used to get something else and, by getting an extra one, you would feel fuller and perhaps would not eat a proper meal afterwards. You could also gain weight if the smoothie is not healthy, so in the end the cost is higher than the benefit.
Therefore, you could easily apply economic concepts, such as the ones described, in your everyday life so as to make decisions that leave you better off. By considering the cost associated with an extra purchase, you could start saving up money. Eventually, you could spend your savings to get a greater benefit. For instance, you could go on vacation without spending your salary and still comply with the payment of your taxes and services.
According to Freud, it occurs during the phallic stage of development which is somewhere between the ages of 3 and 5. According to him, it occurs to all children because they fear the loss of their genitals for some reason. Not many studies have been conducted on this topic.
Answer:
The conclusion is false, because it is assuming that correlation = causation.
Explanation:
An important principle in statistical analysis is the principle that when correlation exist between two variables or more, it does not mean that one of the variables are causing the other to appear in a certain manner.
Remember that correlation means that you are investigating whether a relationships exists between two variables; in this example, as we can see, it is between the biodiversity in an ecosystem and the population of an insect.
The graph can be said to illustrate the result of the research; that as the biodiversity of the ecosystem goes down, the insect's population goes up. This is a form of negative correlation.
However - we do not know what is the direction of the relationship; the student concludes that as some insects die within the ecosystem, the researched insect's population goes up; assuming that the predator species died off and thus the researched insect's population increases.
Yet, it is also possible for the relationship to go towards the other direction; the researched insect population increases - perhaps by the introduction of a new food source that causes the species' population to increase - and thus, this damages the biodiversity of the ecosystem, making the population go down since it is possible that the researched insect is instead the species which is on top of the food chain at that ecosystem.
To investigate the direction of a relationship, further research need to be done and more sophisticated statistical methods need to be used.
