To ensure that all your participants have an equal opportunity to be in either experimental group (one receives a drug, the other group receives a placebo), you decide to toss a coin to determine who gets placed in which group. You have engaged in _______. a. matching b. random assignment c. selective participation d. random sampling e. random participation

Answers

Answer 1

Answer:

random assignment

Explanation:

Random assignment is an experimental technique that seeks to form random and fully randomized experimental groups in relation to the treatments presented in the research. This type of technique prevents the formation of "combined groups" that show the differences to each other and can generate a comprehensive result on the research, thus the random formation of diverse groups that can represent a much larger and different population.

An example of this can be seen in the question above, where the researcher decides the formation of the group that will receive the medicine and the group that will receive the placebo, completely randomly.

Answers

Answer:

D “You are giving others better rates than you are us,” said Mr. Alexander, the representative of  the firm. “We cannot compete if you do that.”

Explanation:

The progressives reformation was a movement that gained ground between the 1890s to the 1920s in the United States of America. At that time wealthy businessmen made their monies through corrupt practices and oppression of the poor laborers. Most times, the government supported them when given bribes.

Answers

Answer:

problem-focused coping strategy

Explanation:

In psychology, Folkman and Lazarus have proposed two different kinds of coping strategies in 1984 including the problem-focused and emotion-focused coping strategies.

In the "problem-focused coping strategy", an individual tries to make various attempts in order to manage or deal with the problems that are causing him or her to experience stress (the things that are responsible for causing stress is referred to as the stressor). The problem-focused coping technique is often used in coping day-to-day problems by identifying a specific problem, thinking of possible solutions, considering costs & benefits associated with the solutions, and at last selecting the best alternative to resolve the problem.

In the question above, the given statement represents "problem-focused coping".

In at least one hundred and fifty words, compare and contrast the philosophies of constitutionalism and the divine right of kings. Which had the greatest impact on the formation of the U.S. Constitution?

Answers

Answer:

Constitutionalism refers to a political structure of a state based on the constitution, as the name itself says. A constitution is the most important legal document in a country, listing the rules and laws that everyone, be it regular people, institutions, or the president himself has to follow. Constitutionalism was created to make people equal, to protect their natural rights and guarantee them liberty in the country they live in.

On the other hand we have the divine right of kings. It is a concept which is quite opposite to that of constitutionalism. As the name itself says, the divine right of kings assumes that king was sent to earth to rule instead of God himself. Given that God doesn't have a physical presence in our world, he has chosen kings to be his representatives on Earth. Thus, the king has every right to do whatever he pleases, without having to think about constitutions, governments, or the feelings of his subjects.

I believe that America is based on the principles of constitutionalism, mostly because it never had a king, but was rather a democratic republic from the very beginning.

If a person has treated you terribly or deeply wronged you in some way, and that person apologizes to you, what should you do? If you accept someone’s apology, does that mean you are being weak? Explain using real-world examples. Must be no less than 10 complete sentences.

Answers

Answer:

if they apologize to you sincerely and they really mean it then for giving them is not a sign of weakness. if the apology seems sloppy and they are not serious then I don't think you should forgive them. It also depends on the situation. If it really hurt you and they kept on doing it when you have told them to stop multiple times then I don't think you should forgive them. You should also be careful, they might be trying to manipulating you.

How did the practice of trick-or-treating develop on Halloween?

Answers

By the ninth century, Christianity had spread into Celtic lands, where it gradually blended with and supplanted older pagan rites. In 1000 A.D. the church designated November 2 as All Souls’ Day, a time for honoring the dead. Celebrations in England resembled Celtic commemorations of Samhain, complete with bonfires and masquerades.  

Poor people would visit the houses of wealthier families and receive pastries called soul cakes in exchange for a promise to pray for the souls of the homeowners’ dead relatives. Known as "souling," the practice was later taken up by children, who would go from door to door asking for gifts such as food, money and ale

Answer:

The practice can be traced to the ancient Celts, early Roman Catholics and 17th-century British politics.
